Cannabis sativa (marijuana, hemp; Cannabaceae) is a medicinal and psychoactive herbal drug. Its unique effects are believed to be caused by cannabinoids, which include Δ9-tetrahydrocannabinol (THC) and more than 80 related metabolites. Medical marijuana and cannabinoid drugs are increasingly used to treat a range of diseases and conditions such as multiple sclerosis and chronic pain.
Currently, the production of cannabinoids for pharmaceutical or other use is through the extraction of cannabinoids from plants, for example Cannabis sativa, or by chemical synthesis.
There are several drawbacks of the natural production and extraction of cannabinoids from plants. It is often difficult to reproduce identical cannabinoid profiles in plants using an extraction process. In addition, extraction from Cannabis sativa produces a mixture of cannabinoids, which can be difficult to purify to provide a single compound needed for pharmaceutical applications.
The chemical synthesis of various cannabinoids is a costly process compared to extraction, but it provides the final product as single pure product, which is often required for pharmaceutical use.
The microbial fermentation-based production of cannabigerolic acid (“CBGA”) or cannabinoids can be more economical, more robust, scalable, and can provide specific cannabinoid products for simplified isolation and purification versus current routes.
There are some known microbial fermentation processes. For example, WO 2016/010827 A1 and WO 2011/017798 A1 describe several processes. However, attempts at reproducing the methods disclosed therein, were unsuccessful: CBGA was not produced.
The methods described in WO 2019/071000 A1, incorporated herein by reference, were successful at producing CGBA, however higher titers of CBGA and various cannabinoids are desired. The inventors have discovered ways to produce cannabinoids as described herein.
All publications, patents, and patent applications herein are incorporated by reference in their entireties to the same extent as if each individual publication, patent, or patent application was specifically and individually indicated to be incorporated by reference in its entirety. In the event of a conflict between a term herein and a term in an incorporated reference, the term herein controls.
This application discloses microorganisms that are capable of producing CBGA and cannabinoids (e.g., THC), in an efficient manner, as well as methods of increasing the efficiency of CBGA and cannabinoid, cannabinoid intermediate, or cannabinoid precursor synthesis (“cannabinoid,” “cannabinoid intermediate,” and “cannabinoid precursor” used interchangibly herein). The products that can be made by the processes and microorganism described herein can include, but are not limited to CBGA, Δ9-tetrahydrocannabinolic acid (THCA), cannabidiolic acid (CBDA), cannabichromenic acid (CBCA), Δ9-tetrahydrocannabinol (THC), cannabidiol (CBD), cannabichromene (CBC), Δ9-tetrahydrocannabivarinic acid (THCVA), cannabidivarinic acid (CBDVA), and cannabichromevarinic acid (CBCVA), as described in WO 2019/071000 (herein incorporated by reference) and as described herein. In some cases, a combination of mutants, deletions and yeast strains may be used as described or in various combinations.

A better understanding of the features and advantages of the present invention will be obtained by reference to the following detailed description that sets forth illustrative embodiments, in which the principles of the invention are utilized, and the accompanying drawings of which:
The following description and examples illustrate embodiments of the invention in detail. It is to be understood that this invention is not limited to the particular embodiments described herein and as such can vary. Those of skill in the art will recognize that there are numerous variations and modifications of this invention, which are encompassed within its scope.
The cannabinoid biosynthetic pathway starts with acyl activating enzyme (AAE1) (also known hexanoyl-CoA synthetase) which converts hexanoic acid to hexanoyl-CoA, which is used as a substrate for a reaction involving two enzymes, polyketide synthase (PKS) and olivetolic acid cyclase (OAC), to form olivetolic acid. Olivetolic acid is then geranylated by a prenyltransferase enzyme (PT) to form cannabigerolic acid (CBGA), a branch-point intermediate that is converted by oxidocyclase enzymes to Δ9-tetrahydrocannabinolic acid (THCA), cannabidiolic acid (CBDA), and cannabichromenic acid (CBCA). These compounds undergo nonenzymatic decarboxylation to their neutral forms, THC and cannabidiol (CBD) and cannabichromene (CBC), respectively. CBGA is a key pathway intermediate that is an important compound for the preparation of both known, commercialized cannabinoids and compounds in development. In some cases, butyric acid is used as a substrate for cannabinoid biosynthesis.
Described herein are genetically modified microorganisms, enzymes, polynucleotides, and methods to more efficiently produce CBGA or cannabinoids, including, THCA, CBDA, CBCA, THC, CBC and CBD.

Natl. Acad. Sci. USA 89: 10915-10919 using a gap opening penalty of 10 and a gap extension penalty of 0.1, so that the highest order match obtained between two sequences wherein at least 50% of the total length of one of the two sequences is involved in the alignment.
The term “polyketide synthase”, “PKS”, “tetraketide synthase”, “olivetol synthase”, “OLS”, “OS” and their grammatical equivalents can be interchangeably used, as they refer to the same enzyme.
A cannabinoid is one of a class of diverse chemical compounds that acts on cannabinoid receptors. Cannabinoids can alter neurotransmitter release in the brain. Ligands for these receptor proteins include the endocannabinoids (produced naturally in the body by animals), the phytocannabinoids (found in cannabis and some other plants), and synthetic cannabinoids (manufactured artificially). The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC), the primary psychoactive compound in cannabis. Cannabidiol (CBD) is another major constituent of the plant. There are at least 113 different cannabinoids isolated from cannabis, exhibiting varied effects.
Cannabinoids can be useful in treating the side effects of cancer and cancer treatment. For example, one of the severe side effects of chemotherapy is loss of appetite. Marinol (containing delta-9-THC API) has been used to effectively treat this side effect. Other medical uses of cannabinoids include but are not limited to anti-inflammatory activity, blocking cell growth, preventing the growth of blood vessels that supply tumors, antiviral activity, and relieving muscle spasms caused by multiple sclerosis.
Disclosed herein are microorganisms and methods of making CBGA or cannabinoids.
The cells that can be used include but are not limited to plant or animal cells, fungus, yeast, algae, or bacterium. The cells can be prokaryotes or in some cases can be eukaryotes. For example, the cell can be a Saccharomyces cerevisiae, Yarrowia lipolytica, or Escherichia coli, or any other cell disclosed throughout.
In certain cases, the cells are not naturally capable of producing CBGA or cannabinoids (e.g., THC, CBD, CBC, THCVA, CBDVA, CBCVA). In some cases, the cells are able to produce CBGA or cannabinoids but at a low level. By implementation of the methods described herein, the cells can be modified such that the level of CBGA or cannabinoids in the cells is higher relative to the level of CBGA or the same cannabinoid produced in the unmodified cells.
In some cases, the modified cell is capable of producing a substrate capable of being converted into a CBGA or a cannabinoid, however, the cells is not capable of naturally producing a cannabinoid. The genetically modified microorganisms in some cases are unable to produce a substrate capable of being converted into a CBGA or a cannabinoid (for example, hexanoic acid), and the substrate capable of being converted into a CBGA or a cannabinoid is provided to the cells as part of the cell's growth medium. In this case, the genetically modified microorganism can process the substrate into a desired product such as CBGA, THC, CBD, or CBC.
The cell can naturally comprise one or more enzyme capable of catalyzing one or more of the reactions: Hexanoyl-CoA to Olivetolic Acid; Olivetolic Acid to CBGA; CBGA to THCA; CBGA to CBDA; CBGA to CBCA; THCA to THC; CBDA to CBD; or CBCA to CBC.
The cell can naturally comprise one or more enzyme capable of catalyzing one or more of the reactions from a substrate such as butyric acid: CBGVA to THCVA; CBGVA to CBDVA; CBGVA to CBCVA; THCVA to THCV; CBDVA to CBDV; or CBCVA to CBCV.
In some cases, the modified cell is capable of producing a substrate capable of being converted into a CBGVA or a cannabinoid, however, the cells is not capable of naturally producing a cannabinoid. The genetically modified microorganisms in some cases are unable to produce a substrate capable of being converted into a CBGVA or a cannabinoid (for example, butyric acid), and the substrate capable of being converted into a CBGVA or a cannabinoid is provided to the cells as part of the cell's growth medium.

In some cases, linkers such as the T2A linker (SEQ ID NO: 15 (amino acid) or 16 (nucleic acid)) can be used.
The fused or linked enzymes can be two or more of any of the enzymes described throughout. For example, the disclosed prenyltransferase can be linked with a CBDA synthase. The resulting fused or linked enzyme can produce increased cannabidiol titers compared to separate enzymes that are not linked or fused. Additionally, other enzymes such as prenyltransferase and THCA synthase can be fused or linked. The resulting fused or linked enzyme can produce increased THC titers compared to separate enzymes that are not linked or fused. Enzymes that can catalyze the product of another enzyme can be fused or linked. For example AAE1 can be fused or linked to PKS. In some cases, OAC can be fused or linked to PKS. This can in some cases, increase the speed of two or more enzymatic conversions due to the proximity of the enzymatic substrates/products.
Vectors
Polynucleotide constructs prepared for introduction into a prokaryotic or eukaryotic host can typically, but not always, comprise a replication system (i.e. vector) recognized by the host, including the intended polynucleotide fragment encoding the desired polypeptide, and can but not necessarily, also include transcription and translational initiation regulatory sequences operably linked to the polypeptide-encoding segment. Expression systems (such as expression vectors) can include, for example, an origin of replication or autonomously replicating sequence (ARS) and expression control sequences, a promoter, an enhancer and necessary processing information sites, such as ribosome-binding sites, RNA splice sites, polyadenylation sites, transcriptional terminator sequences, mRNA stabilizing sequences, nucleotide sequences homologous to host chromosomal DNA, and/or a multiple cloning site. Signal peptides can also be included where appropriate, for example from secreted polypeptides of the same or related species, which allow the protein to cross and/or lodge in cell membranes or be secreted from the cell.
The vectors can be constructed using standard methods (see, e.g., Sambrook et al., Molecular Biology: A Laboratory Manual, Cold Spring Harbor, N.Y. 1989; and Ausubel, et al., Current Protocols in Molecular Biology, Greene Publishing, Co. N.Y, 1995).
The manipulation of polynucleotides that encode the enzymes disclosed herein is typically carried out in recombinant vectors. Numerous vectors are publicly available, including bacterial plasmids, bacteriophage, artificial chromosomes, episomal vectors and gene expression vectors, which can all be employed. A vector can be selected to accommodate a polynucleotide encoding a protein of a desired size. Following recombinant modification of a selected vector, a suitable host cell (e.g., the microorganisms described herein) is transfected or transformed with the vector. Each vector contains various functional components, which generally include a cloning site, an origin of replication and at least one selectable marker gene. A vector can additionally possess one or more of the following elements: an enhancer, promoter, and transcription termination and/or other signal sequences. Such sequence elements can be optimized for the selected host species. Such sequence elements can be positioned in the vicinity of the cloning site, such that they are operatively linked to the gene encoding a preselected enzyme.
Vectors, including cloning and expression vectors, can contain nucleic acid sequences that enable the vector to replicate in one or more selected microorganisms. For example, the sequence can be one that enables the vector to replicate independently of the host chromosomal DNA and can include origins of replication or autonomously replicating sequences. Such sequences are well known for a variety of bacteria, yeast and viruses. For example, the origin of replication from the plasmid pBR322 is suitable for most Gram-negative bacteria, the 2 micron plasmid origin is suitable for yeast, and various viral origins (e.g. SV40, adenovirus) are useful for cloning vectors.
A cloning or expression vector can contain a selection gene (also referred to as a selectable marker). This gene encodes a protein necessary for the survival or growth of transformed microorganisms in a selective culture medium. Microorganisms not transformed with the vector containing the selection gene will therefore not survive in the culture medium. Typical selection genes encode proteins that confer resistance to antibiotics and other toxins, e.g. ampicillin, neomycin, methotrexate, hygromycin, thiostrepton, apramycin or tetracycline, complement auxotrophic deficiencies, or supply critical nutrients not available in the growth media.
The replication of vectors can be performed in E. coli. An E. coli-selectable marker, for example, the β-lactamase gene that confers resistance to the antibiotic ampicillin, can be of use. These selectable markers can be obtained from E. coli plasmids, such as pBR322 or a pUC plasmid such as pUC18 or pUC19, or pUC119.
Some exemplary vectors that can be used in the methods and microorganisms/cells are SEQ ID NO: 3 and 4.

Promoters
Vectors can contain a promoter that is recognized by the host microorganism. The promoter can be operably linked to a coding sequence of interest. Such a promoter can be inducible or constitutive. Polynucleotides are operably linked when the polynucleotides are in a relationship permitting them to function in their intended manner.
Different promoters can be used to drive the expression of the genes. For example, if temporary gene expression (i.e., non-constitutively expressed) is desired, expression can be driven by inducible promoters.
In some cases, some of the genes disclosed can be expressed temporarily. In other words, the genes are not constitutively expressed. The expression of the genes can be driven by inducible or repressible promoters. For example, the inducible or repressible promoters that can be used include but are not limited to: (a) sugars such as arabinose and lactose (or non metabolizable analogs, e.g., isopropyl β-D-1-thiogalactopyranoside (IPTG)); (b) metals such as lanthanum, copper, calcium; (c) temperature; (d) Nitrogen-source; (e) oxygen; (f) cell state (growth or stationary); (g) metabolites such as phosphate; (h) CRISPRi; (i) jun; (j) fos, (k) metallothionein and/or (l) heat shock.
Constitutively expressed promoters can also be used in the vector systems herein. For example, the expression of some of the genes disclosed throughout can be controlled by constitutively active promoters. For examples, the promoters that can be used include but are not limited to p.Bba.J23111, J23111, and J23100.
Promoters suitable for use with prokaryotic hosts can, for example, include but are not limited to the a-lactamase and lactose promoter systems, alkaline phosphatase, the tryptophan (trp) promoter system, the erythromycin promoter, apramycin promoter, hygromycin promoter, methylenomycin promoter and hybrid promoters such as the tac promoter. Promoters for use in bacterial systems will also generally contain a Shine-Dalgarno sequence operably linked to the coding sequence.
Generally, a strong promoter can be employed to provide for high level transcription and expression of the desired product.
One or more promoters of a transcription unit can be an inducible promoter. For example, a GFP can be expressed from a constitutive promoter while an inducible promoter drives transcription of a gene coding for one or more enzymes as disclosed herein and/or the amplifiable selectable marker.
Some vectors can contain prokaryotic sequences that facilitate the propagation of the vector in bacteria. Thus, the vectors can have other components such as an origin of replication (e.g., a nucleic acid sequence that enables the vector to replicate in one or more selected microorganisms), antibiotic resistance genes for selection in bacteria, and/or an amber stop codon which can permit translation to read through the codon. Additional selectable gene(s) can also be incorporated. Generally, in cloning vectors the origin of replication is one that enables the vector to replicate independently of the host chromosomal DNA, and includes origins of replication or autonomously replicating sequences. Such sequences can include the ColEl origin of replication in bacteria or other known sequences.
Genes
The genetically modified microorganisms can comprise a nucleic acid sequence encoding for one or more enzymes that are capable of catalyzing one or more of the following reactions: hexanoic acid to hexanoyl-CoA; hexanoyl-CoA to olivetolic Acid; olivetolic Acid to CBGA; CBGA to THCA; CBGA to CBDA; CBGA to CBCA; THCA to THC; CBDA to CBD; or CBCA to CBC.

The nucleic acid sequence in some cases can be within a vector. In some cases, the nucleic acid sequences do not need to be within a vector but rather integrated into the microorganism's genome or isolated. In some cases, the isolated nucleic acids can be inserted into the genome of the cell/microorganism used. In some cases, the isolated nucleic acid is inserted into the genome at a specific locus, where the isolated nucleic acid can be expressed in sufficient amounts.
In some cases, two or more genes encoding for consecutive enzymes in the pathway from a carbon substrate (e.g., sugar) to any of the cannabinoids described throughout (e.g., THCA, CBDA, CBCA, THC, CBD, or CBC) can be used. In some cases, three or more genes encoding for consecutive enzymes in the pathway can be used. In some cases, four or more genes encoding for consecutive enzymes in the pathway can be used.

The genetically modified microorganisms disclosed herein can have their endogenous genes regulated. This can be useful, for example, when there is negative feedback to the expression of a desired polypeptide, such as any of the enzymes described throughout including but not limited to acyl activating enzyme (AAE1); polyketide synthase (PKS); olivetolic acid cyclase (OAC); prenyltransferase (PT); THCA synthase (THCAS); CBDA synthase (CBDAS), CBCA synthase (CBCAS); HMG-CoA reductase (HMG1); farnesyl pyrophosphate synthetase (ERG20); or any combination thereof. Modifying one or more negative regulator can lead to increased expression of a desired polypeptide, and in some cases, increase the production level of the cannabinoids.
Modifying the expression of endogenous genes can be achieved in a variety of ways. For example, antisense or RNA interference approaches can be used to down-regulate expression of the polynucleotides of the present disclosure, e.g., as a further mechanism for modulating cellular phenotype. That is, antisense sequences of the polynucleotides of the present disclosure, or subsequences thereof, can be used to block expression of naturally occurring homologous polynucleotide sequences. In particular, constructs comprising a desired polypeptide coding sequence, including fragments thereof, in antisense orientation, or combinations of sense and antisense orientation, can be used to decrease or effectively eliminate the expression of the desired polypeptide in a cell or plant and obtain an improvement in shelf life as is described herein. Accordingly, this can be used to “knock-out” the desired polypeptide or homologous sequences thereof. A variety of sense and antisense technologies, e.g., as set forth in Lichtenstein and Nellen (Antisense Technology: A Practical Approach IRL Press at Oxford University, Oxford, England, 1997), can be used. Sense or antisense polynucleotide can be introduced into a cell, where they are transcribed. Such polynucleotides can include both simple oligonucleotide sequences and catalytic sequences such as ribozymes.
Other methods for a reducing or eliminating expression (i.e., a “knock-out” or “knockdown”) of a desired polypeptide in a transgenic cell or plant can be done by introduction of a construct which expresses an antisense of the desired polypeptide coding strand or fragment thereof. For antisense suppression, the desired polypeptide cDNA or fragment thereof is arranged in reverse orientation (with respect to the coding sequence) relative to the promoter sequence in the expression vector. Further, the introduced sequence need not always correspond to the full length cDNA or gene, and need not be identical to the cDNA or gene found in the cell or plant to be transformed.
Additionally, the antisense sequence need only be capable of hybridizing to the target gene or RNA of interest. Thus, where the introduced polynucleotide sequence is of shorter length, a higher degree of homology to the endogenous transcription factor sequence will be needed for effective antisense suppression. While antisense sequences of various lengths can be utilized, in some embodiments, the introduced antisense polynucleotide sequence in the vector is at least 10, 20, 30, 40, 50, 100 or more nucleotides in length in certain embodiments. Transcription of an antisense construct as described results in the production of RNA molecules that comprise a sequence that is the reverse complement of the mRNA molecules transcribed from the endogenous gene to be repressed.
Other methods for a reducing or eliminating expression can be done by introduction of a construct that expresses siRNA that targets a desired polypeptide (e.g., CBGA synthesis polypeptide). In certain embodiments, siRNAs are short (20 to 24-bp) double-stranded RNA (dsRNA) with phosphorylated 5′ ends and hydroxylated 3′ ends with two overhanging nucleotides.
Other methods for a reducing or eliminating expression can be done by insertion mutagenesis using the T-DNA of Agrobacterium tumefaciens or a selection marker cassette or any other non-sense DNA fragments. After generating the insertion mutants, the mutants can be screened to identify those containing the insertion in the CBGA synthesis polypeptide (or other desired polypeptide) gene. Plants containing one or more transgene insertion events at the desired gene can be crossed to generate homozygous plant for the mutation, as described in Koncz et al., (Methods in Arabidopsis Research; World Scientific, 1992).
Suppression of gene expression can also be achieved using a ribozyme. Ribozymes are RNA molecules that possess highly specific endoribonuclease activity. The production and use of ribozymes are disclosed in U.S. Pat. Nos. 4,987,071 and 5,543,508. Synthetic ribozyme sequences including antisense RNAs can be used to confer RNA cleaving activity on the antisense RNA, such that endogenous mRNA molecules that hybridize to the antisense RNA are cleaved, which in turn leads to an enhanced antisense inhibition of endogenous gene expression.
A cell or plant gene can also be modified by using the Cre-lox system (for example, as described in U.S. Pat. No. 5,658,772). A cellular or plant genome can be modified to include first and second lox sites that are then contacted with a Cre recombinase. If the lox sites are in the same orientation, the intervening DNA sequence between the two sites is excised. If the lox sites are in the opposite orientation, the intervening sequence is inverted.
In addition, silencing approach using short hairpin RNA (shRNA) system, and complementary mature CRISPR RNA (crRNA) by CRISPR/Cas system, and virus inducing gene silencing (VIGS) system can also be used to make down regulated or knockout of synthase mutants. Dominant negative approaches can also be used to make down regulated or knockout of desired polypeptides.
The RNA-guided endonuclease can be derived from a clustered regularly interspersed short palindromic repeats (CRISPR)/CRISPR-associated (Cas) system. The CRISPR/Cas system can be a type I, a type II, or a type III system. Non-limiting examples of suitable CRISPR/Cas proteins include Cas3, Cas4, Cas5, Cas5e (or CasD), Cas6, Cas6e, Cas6f, Cas7, Cas8a1, Cas8a2, Cas8b, Cas8c, Cas9, Cask), Cas10d, CasF, CasG, CasH, Csy1, Csy2, Csy3, Cse1 (or CasA), Cse2 (or CasB), Cse3 (or CasE), Cse4 (or CasC), Csc1, Csc2, Csa5, Csn2, Csm2, Csm3, Csm4, Csm5, Csm6, Cmr1, Cmr3, Cmr4, Cmr5, Cmr6, Csb1, Csb2, Csb3, Csx17, Csx14, Csx10, Csx16, CsaX, Csx3, Csz1, Csx15, Csf1, Csf2, Csf3, Csf4, and Cul966.
In general, CRISPR/Cas proteins comprise at least one RNA recognition and/or RNA binding domain. RNA recognition and/or RNA binding domains interact with guide RNAs. CRISPR/Cas proteins can also comprise nuclease domains (i.e., DNase or RNase domains), DNA binding domains, helicase domains, RNAse domains, protein-protein interaction domains, dimerization domains, as well as other domains.
The CRISPR/Cas-like protein can be a wild type CRISPR/Cas protein, a modified CRISPR/Cas protein, or a fragment of a wild type or modified CRISPR/Cas protein. The CRISPR/Cas-like protein can be modified to increase nucleic acid binding affinity and/or specificity, alter an enzyme activity, and/or change another property of the protein. For example, nuclease (i.e., DNase, RNase) domains of the CRISPR/Cas-like protein can be modified, deleted, or inactivated. Alternatively, the CRISPR/Cas-like protein can be truncated to remove domains that are not essential for the function of the fusion protein. The CRISPR/Cas-like protein can also be truncated or modified to optimize the activity of the effector domain of the fusion protein.
One method to silence a desired gene (or a CBGA synthesis polypeptide gene) is virus induced gene silencing (known to the art as VIGS). In general, in plants infected with unmodified viruses, the viral genome is targeted. However, when viral vectors have been modified to carry inserts derived from host genes (e.g. portions of sequences encoding a desired polypeptide such as CBGA synthesis polypeptide), the process is additionally targeted against the corresponding mRNAs. Thus disclosed is a method of producing a plant expressing reduced levels of a desired gene (such as CBGA synthesis polypeptide) or other desired gene(s), the method comprising (a) providing a plant expressing a desired gene (e.g., a CBGA synthesis polypeptide); and (b) reducing expression of the desired gene in the plant using virus induced gene silencing.
In some cases, one or more genes can be disrupted. In some cases, the one or more genes can be from the pathway that controls beta oxidation of long chain fatty acids. For example, in some cases, the one or more genes that can be disrupted can be any one of FOX1, FAA1, FAA4, FAT1, PXA1, PXA2, and/or PEX11. Any of the methods described throughout, can be used to disrupt one or more of the genes.
In some cases, the one or more genes that can be disrupted can comprise FOX1. For example, a sequence that is substantially identical to SEQ ID NO: 39 can be targeted for disruption. Any of the methods described throughout, can be used to disrupt the FOX1 gene, for example, but use of the CRISPR/Cas system or the use of RNAi technology. As few as a single nucleotide needs to be altered to have a disruptive effect to FOX1 or other genes that are targeted for disruption.

Reaction conditions that should be considered include temperature, media flow rate, pH, media redox potential, agitation rate (if using a continuous stirred tank reactor), inoculum level, maximum substrate concentrations and rates of introduction of the substrate to the bioreactor to ensure that substrate level does not become limiting, and maximum product concentrations to avoid product inhibition.
In some cases, non-genetically modified microorganisms can be used to increase CBGA or cannabinoid production. For example, cells taken from organisms that naturally produce cannabinoids can be used. These cells can be isolated and once isolated they can be used in a fermentation process.
The fermentation conditions described herein are applicable to any and all methods disclosed throughout the application.
pH can have a profound effect on overall CBGA, CBGVA or cannabinoid production. Therefore, pH adjustments should be made in some cases.
In some cases, the pH during fermentation can vary from 4 to 10. In some instances, the pH can be from 5 to 9; 6 to 8; 6.1 to 7.9; 6.2 to 7.8; 6.3 to 7.7; 6.4 to 7.6; or 6.5 to 7.5. For example, the pH can be from 6.6 to 7.4. In some instances, the pH can be from 5 to 9. In some instances, the pH can be from 6 to 8. In some instances, the pH can be from 6.1 to 7.9. In some instances, the pH can be from 6.2 to 7.8. In some instances, the pH can be from 6.3 to 7.7. In some instances, the pH can be from 6.4 to 7.6. In some instances, the pH can be from 5.5 to 7.5. In some instances, the pH can be from 6.5 to 7.5. In some instances the pH used for the fermentation can be greater than 6. In some instances the pH used for the fermentation can be lower than 10.
Temperature
Temperature can also be adjusted based on cell, microorganism, or enzyme sensitivity. For example, the temperature used during fermentation, can from 27° C. to 45° C. In other instances, the temperature of the fermentation can be from 27° C. to 45° C.; 28° C. to 44° C.; 29° C. to 43° C.; 30° C. to 42° C.; 31° C. to 41° C.; 32° C. to 40° C. For example, the temperature can be from 36° C. to 39° C. (e.g., 36° C., 37° C., 38° C., or 39° C. In some instances, the temperature can be from 27° C. to 45° C. In some instances, the temperature can be from 28° C. to 44° C. In some instances, the temperature can be from 29° C. to 43° C. In some instances, the temperature can be from 30° C. to 42° C. In some instances, the temperature can be from 31° C. to 41° C. In some instances, the temperature can be from 32° C. to 40° C.
Gases
Availability of oxygen and other gases such as gaseous CO2 can affect yield and fermentation rate. For example, when considering oxygen availability, the percent of dissolved oxygen (DO) within the fermentation media can be from 1% to 40%. In certain instances, the DO concentration can be from 1.5% to 35%; 2% to 30%; 2.5% to 25%; 3% to 20%; 4% to 19%; 5% to 18%; 6% to 17%; 7% to 16%; 8% to 15%; 9% to 14%; 10% to 13%; or 11% to 12%. For example, in some cases the DO concentration can be from 2% to 30%. In other cases, the DO can be from 3% to 20%. In some instances, the DO can be from 4% to 10%. In some cases, the DO can be from 1.5% to 35%. In some cases, the DO can be from 2.5% to 25%. In some cases, the DO can be from 4% to 19%. In some cases, the DO can be from 5% to 18%. In some cases, the DO can be from 6% to 17%. In some cases, the DO can be from 7% to 16%. In some cases, the DO can be from 8% to 15%. In some cases, the DO can be from 9% to 14%. In some cases, the DO can be from 10% to 13%. In some cases, the DO can be from 11% to 12%.
For example, when considering atmospheric CO2, the percent of atmospheric CO2 within an incubator can be from 0% to 10%. In some cases, atmospheric CO2 can help to control the pH within cell culture medium. pH contain within cell culture media is dependent on a balance of dissolved CO2 and bicarbonate (HCO3). Changes in atmospheric CO2 can alter the pH of the medium. In certain instances, the atmospheric CO2 can be from 0% to 10%; 0.01% to 9%; 0.05% to 8%; 0.1% to 7%; 0.5% to 6%; 1% to 5%; 2% to 4%; 3% to 6%; 4% to 7%; 2% to 6%; or 5% to 10%. For example, in some cases the atmospheric CO2 can be from 0% to 10%. In other cases, the atmospheric CO2 can be from 0.01% to 9%. In some instances, the atmospheric CO2 can be from 0.05% to 8%. In some cases, the atmospheric CO2 can be from 0.1% to 7%. In some cases, the atmospheric CO2 can be from 0.5% to 6%. In some cases, the atmospheric CO2 can be from 1% to 5%. In some cases, the atmospheric CO2 can be from 2% to 4%. In some cases, the atmospheric CO2 can be from 3% to 6%. In some cases, the atmospheric CO2 can be from 4% to 7%.

Product Recovery
The fermentation of the microorganisms disclosed herein can produce a fermentation broth comprising a desired product (e.g., CBGA, CBGVA, THCA, CBDA or CBCA or cannabinoid) and/or one or more by-products as well as the cells/microorganisms (e.g., a genetically modified microorganism), in a nutrient medium.
In certain embodiments the CBGA, THCA, CBDA or CBCA produced in the fermentation reaction is converted to a cannabinoid, such as THC, CBD, and/or CDC. This conversion can happen directly from the fermentation broth. However, in other embodiments, the CBGA, THCA, CBDA or CBCA can be first recovered from the fermentation broth before conversion to a cannabinoid such as THC, CBD, and/or CDC. In certain embodiments the CBGVA produced in the fermentation reaction is converted to a cannabinoid, such as THCC, CBDV, and/or CDCV. This conversion can happen directly from the fermentation broth. However, in other embodiments, the CBGVA can be first recovered from the fermentation broth before conversion to a cannabinoid such as THCV, CBDV, and/or CDCV.
In some cases, the CBGA, CBGVA, THCA, CBDA or CBCA can be continuously removed from a portion of broth and recovered as purified the CBGA. In particular embodiments, the recovery of the CBGA, CBGVA, THCA, CBDA or CBCA includes passing the removed portion of the broth containing the CBGA, CBGVA, THCA, CBDA or CBCA through a separation unit to separate the microorganisms (e.g., genetically modified microorganism) from the broth, to produce a cell-free CBGA, CBGVA, THCA, CBDA or CBCA containing permeate, and returning the microorganisms to the bioreactor. Additional nutrients can be added to the media to replenish its nutrients before it is returned to the bioreactor. The cell-free CBGA, CBGVA, THCA, CBDA or CBCA permeate can then be stored or be used for subsequent conversion to cannabinoids (or other desired product).
Also, if the pH of the broth was adjusted during recovery of CBGA CBGVA, THCA, CBDA or CBCA the pH should be re-adjusted to a similar pH to that of the broth in the fermentation bioreactor, before being returned to the bioreactor.
Subsequent purification steps can involve treating the post-fermentation CBGA, CBGVA, THCA, CBDA or CBCA product using methods known in the art to recover individual product species of interest to high purity.
In one example, CBGA, CBGVA, THCA, CBDA or CBCA extracted in an organic phase can be transferred to an aqueous solution. In some cases, the organic solvent can be evaporated by heat and/or vacuum, and the resulting powder can be dissolved in an aqueous solution of suitable pH. The aqueous phase can then be removed by decantation, centrifugation, or another method. For example, when the organic solvent is ethyl acetate, the resulting powder from evaporation is dissolved in a water:acetonitrile mixture (50:50 ratio).
The same methods as described above can be applied to cannabinoids, should they be produced.
The microorganisms and the methods herein can produce CBGA, CBGVA, THCA, CBDA, CBCA or cannabinoids at surprisingly high efficiency, more so than other known CBGA, CBGVA, THCA, CBDA, CBCA or cannabinoids fermentation processes. For example, the microorganisms and the methods disclosed herein can convert a carbon substrate (such as sugar, alcohol, and/or fatty acid) at a rate of greater than 0.01%.
The genetic modifications to the cells described throughout can be made to produce CBGA, CBGVA, THCA, CBDA, CBCA or cannabinoids over what would have been made without any genetic modifications. For example, compared to a non-genetically altered cell, the genetically modified microorganisms described throughout can produce CBGA, CBGVA, THCA, CBDA, CBCA or cannabinoids greater than 1.1 times (compared to the production levels of a non-genetically modified microorganism or non-genetically altered cell).
In some cases, the cannabinoid can be THC, CBD, CBC, or any combination thereof. In other cases, the cannabinoid can be THCV, CBDV, CBCV, or any combination thereof.
Methods of Making CBGA, THCA, CBDA or CBCA or cannabinoids
The genetically modified cells or microorganisms described throughout can be used to make CBGA, THCA, CBDA, CBCA and/or cannabinoids, e.g., THC, CBD, and CBC. A substrate capable of being converted into a CBGA or a cannabinoid can be brought in contact with one or more of the following enzymes: acyl activating enzyme (AAE1); polyketide synthase (PKS); olivetolic acid cyclase (OAC); prenyltransferase (PT); THCA synthase (THCAS); CBDA synthase (CBDAS), CBCA synthase (CBCAS), HMG-Co reductase (HMG1), and/or farnesyl pyrophosphate synthetase (ERG20).
The CBGA, THCA, CBDA, CBCA or cannabinoids (e.g., THC, CBD, CBC) produced can be recovered and isolated from the modified cells. The CBGA, THCA, CBDA, CBCA or cannabinoids in some cases can be secreted into the media of a cell culture, in which the CBGA, THCA, CBDA, CBCA or cannabinoids is extracted directly from the media. In some cases, the CBGA, THCA, CBDA, CBCA or cannabinoids can be within the cell itself, and the cells will need to be lysed in order to recover the respective CBGA, THCA, CBDA, CBCA or cannabinoids. In some instances, both cases can be true, where some CBGA, THCA, CBDA, CBCA or cannabinoids are secreted and some remains within the cells. In this case, either method or both methods can be used.
The genetically modified cells or microorganisms described throughout can be used to make CBGVA and/or cannabinoids, e.g., THCV, CBDV, and CBCV. A substrate capable of being converted into a CBGVA or a cannabinoid can be brought in contact with one or more of the following enzymes: acyl activating enzyme (AAE1); polyketide synthase (PKS); olivetolic acid cyclase (OAC); prenyltransferase (PT); THCA synthase (THCAS); CBDA synthase (CBDAS), CBCA synthase (CBCAS), HMG-Co reductase (HMG1), and/or farnesyl pyrophosphate synthetase (ERG20).
The CBGVA or cannabinoids (e.g., THCV, CBDV, CBCV) produced can be recovered and isolated from the modified cells. The CBGVA or cannabinoids in some cases can be secreted into the media of a cell culture, in which the CBGVA or cannabinoids is extracted directly from the media. In some cases, the CBGVA or cannabinoids can be within the cell itself, and the cells will need to be lysed in order to recover the respective CBGVA or cannabinoids. In some instances, both cases can be true, where some CBGVA or cannabinoids are secreted and some remains within the cells. In this case, either method or both methods can be used.
Accordingly, disclosed herein is a method of making CBGA, CBGVA, THCA, CBDA, CBCA or a cannabinoid comprising (a) contacting the genetically modified microorganism with a medium comprising a carbon source, and (b) growing the genetically modified microorganism to produce the CBGA or cannabinoid. The genetically modified microorganism can comprise any microorganism disclosed throughout. For example, the microorganism can be a genetically modified microorganism capable of converting a carbon substrate into CBGA, CBGVA, THCA, CBDA, CBCA or a cannabinoid, the genetically modified microorganism comprising a heterologous nucleic acid encoding one or more of the enzymes disclosed throughout (e.g., microorganism can comprise a nucleic acid sequence encoding for one or more of the following enzymes: acyl activating enzyme (AAE1); polyketide synthase (PKS); olivetolic acid cyclase (OAC); prenyltransferase (PT); THCA synthase (THCAS); CBDA synthase (CBDAS), CBCA synthase (CBCAS); HMG-Co reductase (HMG1); farnesyl pyrophosphate synthetase (ERG20); or any combination thereof).
The carbon source can be any carbon source that can be used by the microorganism. In some cases, the carbon source can be a sugar, alcohol, and/or fatty acid. For example, the sugar, alcohol or fatty acid can include without limitation hexanoic acid, butyric acid, glucose, fructose, xylose, sucrose, dextrins, starch, xylan, cellulose, hemicellulose, arabinose, glycerol, ethanol, butanol, methanol, or any combination thereof. In some cases, the carbon source can be hexanoic acid. In some cases, the carbon source can be olivetolic acid. In other cases, the carbon source can be a mixture of one or more different types of carbon sources.
The cannabinoid produced by the methods disclosed throughout can be any cannabinoid including but not limited to Δ9-tetrahydrocannabinolic acid (THCA), cannabigerolic acid (CBGA); cannabidiolic acid (CBDA), cannabichromenic acid (CBCA), Δ9-tetrahydrocannabinol (THC), cannabidiol (CBD), cannabichromene (CBC), Δ9-tetrahydrocannabivarinic acid (THCVA), cannabidivarinic acid (CBDVA), cannabichromevarinic acid (CBCVA) or any combination thereof.
In some cases, the medium does not contain any cells. In other words, this reaction is performed in the media in vitro. In some cases, the reaction does not occur within a cell. For example, the conversion of hexanoic acid to hexanoyl-CoA can occur outside of a cell. In some cases, the conversion of hexanoyl-CoA to olivetolic acid can occur outside of a cell. In some cases, the conversion of olivetolic acid to CBGA can occur outside of a cell. In some cases, the conversion of CBGA to Δ9-tetrahydrocannabinolic acid can occur outside of a cell. In some cases, the conversion of Δ9-tetrahydrocannabinolic acid to Δ9-tetrahydrocannabinol can occur outside of a cell. In some cases, the conversion of CBGA to cannabidiolic acid can occur outside of a cell. In some cases, the conversion of cannabidiolic acid to cannabidiol can occur outside of a cell. In some cases, the conversion of CBGA to cannabichromenic acid can occur outside of a cell. In some cases, the conversion of cannabichromenic acid to cannabichromene can occur outside of a cell.
In some cases, the cannabinoid, such as CBGA, CBGVA, THCA, CBDA, or CBCA can be converted outside of a cell. For example, once CBGA, CBGVA, THCA, CBDA, or CBCA is produced, it can be either isolated (from the cell or the cell media or both). Once isolated it can be converted, enzymatically or non-enzymatically into other a different product, such as another type of cannabinoid. In some cases, the CBGA, CBGVA, THCA, CBDA, or CBCA is just secreted into the media by the microorganism that synthesized it, and then the CBGA, CBGVA, THCA, CBDA, or CBCA is directly converted enzymatically or non-enzymatically into other a different product, such as another type of cannabinoid.
In some cases, this reaction is contained within a cell that is within cell culture media. In other words, the reaction is performed in vivo. For example, the conversion of hexanoic acid to hexanoyl-CoA can occur within a cell. In some cases, the conversion of hexanoyl-CoA to olivetolic acid can occur within a cell. In some cases, the conversion of olivetolic acid to CBGA can occur within a cell. In some cases, the conversion of CBGA to Δ9-tetrahydrocannabinolic acid can occur within a cell. In some cases, the conversion of Δ9-tetrahydrocannabinolic acid to Δ9-tetrahydrocannabinol can occur within a cell. In some cases, the conversion of CBGA to cannabidiolic acid can occur within a cell. In some cases, the conversion of cannabidiolic acid to cannabidiol can occur within a cell. In some cases, the conversion of CBGA to cannabichromenic acid can occur within a cell. In some cases, the conversion of cannabichromenic acid to cannabichromene can occur within a cell.
In some cases, there is a combination of the two. Some reactions along the pathway can occur within a cell, whereas some of the reactions along the pathway occur outside of a cell.
In some cases, the medium is cell culture media. In other instances, the medium is water or other liquid in which the cells (for in vivo reactions) can survive (such as saline buffered water). In other instances, the medium is water or other liquid in which the enzymes (for in vitro reactions) are active.

In another example, purified CB GVA can be used as a feedstock to make other cannabinoids such as THCVA, CBDVA, CBCVA, THCV, CBDV, and CBCV.
The cannabinoids made in the processes described throughout can be used to manufacture medicinal compounds. Accordingly, in one aspect, disclosed is a use of cannabinoids as a feedstock compound in the manufacture of a medicinal compound. For example, the cannabinoids can be subsequently processed to prepare a pharmaceutical formulation.
The cannabinoids also include pharmaceutically acceptable derivatives thereof. A “pharmaceutically acceptable derivative” means any pharmaceutically acceptable salt, ester, salt of an ester, or other derivative thereof.
Pharmaceutically acceptable salts of the compounds of this invention include those derived from pharmaceutically acceptable inorganic and organic acids and bases.

In addition, by way of example only, parenteral delivery includes intramuscular, subcutaneous, intravenous, intramedullary injections, as well as intrathecal, direct intraventricular, intraperitoneal, intralymphatic, and intranasal injections.
One particular delivery system can be through the pulmonary system. In some cases, the cannabinoid can be for into a liquid and vaporized so that it can be inhaled. See e.g., U.S. Pat. No. 9,326,967. Vaporization of cannabinoids and delivery through the pulmonary system can result in quick absorption through the circulatory system and can provide extremely fast systemic effects. Further, vaporization can mimic one of the preferred ways in which natural cannabinoids are inhaled.
Additional delivery system that can work by intravenous injections. See e.g., WO2013009928A1. Similar to vaporization, this intravenous injection can provide extremely fast systemic effects.
Oral delivery systems, such as, delivery through the gastrointestinal tract, can be used to deliver the cannabinoids. For example, the oral delivery system can be in the form of a pharmaceutical dosage unit, food, drink, or anything that can be delivered through the gastrointestinal tract.
Treatment of Disease and Symptoms of Disease
The cannabinoids can be used to treat disease, in particular to treat disease of people that are in need thereof. This includes treating one or more symptoms of the diseases. For example, the cannabinoids can be used to treat one of more of the following diseases: anorexia, multiple sclerosis, neurodegenerative disorders, such as Parkinson's disease, Huntington's disease, Tourette's syndrome, and Alzheimer's disease, epilepsy, glaucoma, osteoporosis, schizophrenia, bipolar disorder, post-traumatic stress disorder (PTSD), asthma, cardiovascular disorders, cancer, obesity, or metabolic syndrome-related disorders.
The cannabinoids can be used to treat one or more symptoms of disease, such as depression, anxiety, insomnia, emesis, pain, or inflammation.
Some of the diseases or symptom of disease can be exclusive to humans, but other diseases or symptom of disease can be shared in more than one animal, such as in all mammals.
The cannabinoids produced by the microorganism and methods described throughout can be used for recreational use. For example, the cannabinoids, such as Δ9-tetrahydrocannabinolic acid (THCA), cannabidiolic acid (CBDA), cannabichromenic acid (CBCA), Δ9-tetrahydrocannabinol (THC), cannabidiol (CBD), cannabichromene (CBC), Δ9-tetrahydrocannabivarinic acid (THCVA), cannabidivarinic acid (CBDVA), cannabichromevarinic acid (CBCVA), or any combination thereof, can be used for non-medical uses.
In some cases, the cannabinoid can be formed into a liquid and vaporized so that it can be inhaled. See e.g., U.S. Pat. No. 9,326,967. Vaporization of cannabinoids and delivery through the pulmonary system can be used and can be preferred by some recreational users. For example, recreational users who do not like the smell of burning cannabis or those that are afraid of the effects of inhaling burning substances, can use this method. Further, since this method is not invasive and can be used almost anywhere, recreational users can prefer this method.
In some cases, the cannabinoid can be formed into something that can be injected, e.g., injected intravenously. This method can be used in order to deliver substances quickly and efficiently within the blood stream. For example, this liquid can be injected into the saline solution (colloquially known as “IV”) used in hospitals to keep patients hydrated. Further, intravenous injections can be used by recreational users for immediate effects. In some cases, the intravenous cannabinoid injections can be used to treat other drug addictions, such as heroin addiction.
In additional cases, the cannabinoids produced from the microorganisms and methods described throughout can be used as an additive to food or drink. For example, the cannabinoids can be used, for example, in baked goods, such as brownies or cakes. Additionally, the cannabinoids can be added to a beverage such as water, soda, beer, liquor, etc.
Other recreational ways to use the cannabinoids include but are not limited to patches; (similar to nicotine patches); topically (such as in lotions); sprays (breath freshener), or tinctures (mouth drops).
The disclosure is now described with reference to the following examples. These examples are provided for the purpose of illustration only and the disclosure should in no way be construed as being limited to these examples, but rather should be construed to encompass any and all variations which become evident as a result of the teaching provided herein.
A prenyltransferase of interest was identified. The amino acid sequence (SEQ ID NO: 1) was used by Genscript to design and synthesize the yeast codon optimized sequence coding for the prenyltransferase and used in the experiments.
Plasmids were constructed using the GeneArt Seamless Cloning and Assembly from Thermo Fisher Scientific. The RUNM000898_511.1 vector (SEQ ID NO: 3) contained the Saccharomyces cerevisiae 2μ replication origin, the URA3 gene as an auxotrophic marker and the PKS and OAC genes under the regulation of the bidirectional GAL1/GAL10 promoter. The bCBGA0098 vector (SEQ ID NO: 4) contained the Saccharomyces cerevisiae 2μ replication origin, the LEU2 gene as an auxotrophic marker and the AAE1 and PT genes under the regulation of the bidirectional GAL1/GAL10 promoter. The bCBGA0306 vector (SEQ ID NO: 25) contained the Saccharomyces cerevisiae 2μ replication origin, the LEU2 gene as an auxotrophic marker and the PT gene under the regulation of the bidirectional GAL1/GAL10 promoter.
The parental strain for all examples was the Saccharomyces cerevisiae CEN.PK2-1C strain. Its genotype is: MATA, ura3-52; trp1-289; leu2-3,112; his3Δ 1; MAL2-8C; SUC2.
A mutant ERG20 allele was integrated into the GAL80 locus of the host. First, a plasmid was constructed carrying an ERG20 allele with two mutations: F96W and N127W. Second, the ERG20 allele together with the adjacent HygMX cassette was amplified in a PCR reaction and flanking sequences of the chromosomal GAL80 coding sequence were incorporated during the PCR reaction using oligonucleotides with 5′ extensions. Third, this DNA fragment was transformed into the host strain by electroporation. Finally, the strain with integrated mutant ERG20 sequence at the GAL80 locus were identified by its hygromycin B resistance and referred to as yCBGA0172.
Plasmids RUNM000898_511.1 (SEQ ID NO: 3) and bCBGA0098 (SEQ ID NO: 4) were transformed into the yCBGA0172 strain by electroporation. Transformants were selected by their leucine and uracil prototrophy on SD/MSG minimal medium (20 g/L glucose, 1.7 g/L yeast nitrogen base w/o ammonium sulphate and amino acids, 1 g/L monosodium glutamic acid, 20 g/L agar when solid medium is to be used) supplemented with histidine and tryptophan.
In another example plasmid bCBGA0306 (SEQ ID NO: 25) and the VVN4655922 plasmid were transformed into the yCBGA0172 strain by electroporation. The plasmid VVN4655922 encodes for the Saccharomyces cerevisiae HMG1 gene truncated of the first 530 amino acids and has the Saccharomyces cerevisiae TRP1 gene as an auxotrophic selection marker. Transformants were selected by their leucine and tryptophan prototrophies on SD/MSG minimal medium supplemented with histidine and uracil.
Transformant colonies were picked and inoculated into separate wells of a 96-well deep well plate. Each well contained 400 μl Synthetic Defined (SD)/MSG liquid medium supplemented with histidine and tryptophan. These inoculums were grown overnight at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter.
After the overnight growth the samples were centrifuged, the supernatant discarded and cells transformed with plasmids RUNM000898_511.1 and bCBGA0098 were re-suspended in 400 μl YPD-HXA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 100 mg/L hexanoic acid) medium. In case of cultures transformed with plasmids bCBGA0306 and VVN4655922 the pelleted cells were re-suspended in 400 μl YPD-OLA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 40 mg/L olivetolic acid) medium.
Then samples were grown for 16 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 16 μl 50% glucose was added to the samples. Samples grown in YPD-OLA medium were supplemented additionally with 20 μl of 800 mg/L olivetolic acid solution too.
Finally, samples were grown for additional 32 hours and were analyzed for CBGA titers.
The samples were processed by adding 400 μl acetonitrile, then shaken for 5 minutes at 30° C. at 300 rpm with 50 mm throw. The samples were then centrifuged at 400 rpm for 5 minutes. 200 μl of supernatant were transferred into a new 96 well plate.
The new 96 well plate were transferred to a Waters Acquity UPLC (Binary pump)-TQD MS and set with the following parameters:
Using the strains and methods described above CBGA was produced at 200 μg/L concentration when YPD-HXA medium was used and at 15 mg/L concentration when YPD-OLA medium was used. A representative chromatogram of the sample and the CBGA standard can be seen in
A modified sequence with higher prenyl transferase activity was constructed and referred to as GFP-dPT (polynucleotide sequence: SEQ ID NO: 26; amino acid sequence: SEQ ID NO: 27). The GFP-dPT gene is a fusion of two polynucleotide sequences: a gene of a modified fluorescent protein yEVenus (SEQ ID NO: 28) from the plasmid pKT90 and a truncated version of SEQ ID NO: 2 missing its first 246 nucleotides.
Plasmids were constructed using the GeneArt Seamless Cloning and Assembly from Thermo Fisher Scientific. The bCBGA0385 vector (SEQ ID NO: 29) contained the Saccharomyces cerevisiae 2μ replication origin, the LEU2 gene as an auxotrophic marker and the GFP-dPT gene under the regulation of the bidirectional GAL1/GAL10 promoter. The bCBGA0305 vector (SEQ ID NO: 30) contained the Saccharomyces cerevisiae 2μ replication origin, the TRP1 gene as an auxotrophic marker and the AAE1 gene under the regulation of the bidirectional GAL1/GAL10 promoter.
For testing the GFP-dPT activity a new parental strain was constructed: a polynucleotide fragment of the RUNM000898_511.1 vector coding for OAC, PKS and URA3 genes was transformed into the strain yCBGA0172 by electroporation. The strain with OAC, PKS and URA3 genes inserted was identified by its uracil prototrophy on SD/MSG minimal medium supplemented with histidine, tryptophan and leucine and referred to as yCBGA0189.
In an another experiment a polynucleotide fragment coding for the truncated version of HMG1 gene lacking its first 530 amino acids and a KanMX cassette was transformed into the strain yCBGA0172 by electroporation. The strain with truncated HMG1 gene inserted was identified by its G418 resistance and referred to as yCBGA0197.
The strain yCBGA0197 was transformed with a vector coding for the Saccharomyces cerevisiae HO gene and URA3 gene. The plasmid was cured and a clone with MAT alpha mating type was identified using standard laboratory methods. Finally, this MAT alpha clone was mated with yCBGA0189 and the isolated diploid strain is referred to as yCBGA0201.
Plasmids bCBGA0305 and bCBGA0385 were transformed into the yCBGA0201 strain by electroporation. Transformants were selected by their leucine and tryptophan prototrophies on SD/MSG minimal medium supplemented with histidine.
In another example, plasmid bCBGA0385 was transformed into the yCBGA0197 strain by electroporation. Transformants were selected by their leucine prototrophy on SD/MSG minimal medium supplemented with histidine, uracil and tryptophan.
Transformant colonies were picked and inoculated into separate wells of a 96-well deep well plate. Each well contained 400 μl SD/MSG liquid medium supplemented with histidine in case of strains containing both bCBGA0305 and bCBGA3085 and with histidine, uracil and tryptophan in case of strains containing bCBGA0385 plasmid alone. These inoculums were grown overnight at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter.
After the overnight growth the samples were centrifuged, the supernatant discarded and cells re-suspended in 400 μl YPD-HXA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 100 mg/L hexanoic acid) medium or 400 μl YPD-800LA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 80 mg/L olivetolic acid) medium. In case of cultures transformed with only bCBGA0385 plasmid the YPD-800LA medium was used.
The samples were grown for 16 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 16 μl 50% glucose was added to the samples.
Finally, samples were grown for additional 32 hours and were analyzed for CBGA titers as described in “Example 4—Sample processing and analytics”.
Using the strains and methods described above CBGA was produced at 11 mg/L concentration when YPD-HXA medium was used and at 50 mg/L concentration when YPD-800LA medium was used.
Another modified sequence with increased prenyl transferase activity was constructed and referred to as ERG20mut-dPT (polynucleotide sequence: SEQ ID NO: 31; amino acid sequence: SEQ ID NO: 32). The ERG20mut-dPT gene is a fusion of two polynucleotide sequences: ERG20 gene with F96W and N127W mutations and a truncated version of SEQ ID NO: 2 missing its first 246 nucleotides.
Plasmid was constructed using the GeneArt Seamless Cloning and Assembly from Thermo Fisher Scientific. The bCBGA0559 vector (SEQ ID NO: 33) contained the Saccharomyces cerevisiae 2μ replication origin, the LEU2 gene as an auxotrophic marker and the ERG20mut-dPT gene under the regulation of the bidirectional GAL1/GAL10 promoter.
bCBGA0559 was transformed into the yCBGA0197 strain by electroporation. Transformants were selected by their leucine prototrophy on SD/MSG minimal medium supplemented with histidine, uracil and tryptophan.
Transformant colonies were picked and inoculated into separate wells of a 96-well deep well plate. Each well contained 400 μl SD/MSG liquid medium supplemented with histidine, uracil and tryptophan. These inoculums were grown overnight at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter.
After the overnight growth the samples were centrifuged, the supernatant discarded and cells re-suspended in 400 μl YPD-1200LA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 120 mg/L olivetolic acid) medium.
Then samples were grown for 16 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 16 μl 50% glucose was added to the samples.
Finally, samples were grown for additional 32 hours and were analyzed for CBGA titers as described in Example 4—Sample processing and analytics.
Using the strains and methods described above CBGA was produced at 90 mg/L concentration.
yCBGA0237 strain was constructed by deleting the HygMX and KanMX cassettes from the yCBGA0197 strain and inserting the GFP-dPT gene under the regulation of the bidirectional GAL1/GAL10 promoter into the YJL144W locus by replacing the native YJL144W open reading frame (ORF). Two more strains were constructed by deleting different fragments from the promoter of the native ERG20 allele of the yCBGA0237 strain. The yCBGA0253 strain contains a 133 nucleotide long deletion between 143 and 275 nucleotides upstream of the translational start site. The yCBGA0254 strain contains a 422 nucleotide long deletion between 69 and 490 nucleotides upstream of the translational start site.
Strains yCBGA0237, yCBGA0253 and yCBGA0254 were inoculated into separate wells of a 96-well deep well plate. Each well contained 400 μl SD/MSG liquid medium supplemented with histidine, leucine, uracil and tryptophan. These inoculums were grown overnight at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter.
After the overnight growth 40 μl of the samples were transferred into 360 μl YPD-1200LA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 120 mg/L olivetolic acid) medium.
Then samples were grown for 16 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 16 μl 50% glucose was added to the samples.
Finally, samples were grown for additional 32 hours and were analyzed for CBGA titers as described in Example 4—Sample processing and analytics.
Using the strains and methods described above, yCBGA0237 strain produced 53 mg/L CBGA and yCBGA0253 and yCBGA0254 reached 96 and 78 mg/L CBGA concentration, respectively.
A plasmid was constructed using the GeneArt Seamless Cloning and Assembly from Thermo Fisher Scientific. The RUNM001233_51.1 vector (SEQ ID NO: 34) contained the Saccharomyces cerevisiae 2μ replication origin, the URA3 gene as an auxotrophic marker and the THCA synthase gene under the regulation of the bidirectional GAL1/GAL10 promoter.
For testing the olivetolic acid conversion into THCA the RUNM001233_51.1 and bCBGA0385 vectors were transformed into the strain yCBGA0197 by electroporation. Transformants were selected by their leucine and uracil prototrophies on SD/MSG minimal medium supplemented with histidine and tryptophan.
Transformant colonies were picked and inoculated into separate wells of a 96-well deep well plate. Each well contained 400 μl SC-URA-LEU (6.7 g/L Yeast Nitrogen Base, 1.6 g/L Amino Acid Drop Out mix without uracil and leucine, 22 g/L glucose, buffered to pH 6.0). These inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter.
After the 48 hours growth period the samples were centrifuged, the supernatant discarded and cells re-suspended in 400 μl YPD-1200LA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 120 mg/L olivetolic acid) medium.
Then samples were grown for 16 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 16 μl 50% glucose was added to the samples.
Finally, samples were grown for additional 32 hours and were analyzed for THCA and CBGA titers as described below.
Using the strains and methods described above CBGA was produced at 2 mg/L concentration while THCA was produced at 84 mg/L concentration.
Plasmids were constructed using the GeneArt Seamless Cloning and Assembly from Thermo Fisher Scientific. The RUNM001210_96.1 vector (SEQ ID NO: 35) contained the Saccharomyces cerevisiae 2μ replication origin, the URA3 gene as an auxotrophic marker, the PKS and OAC genes under the regulation of the bidirectional GAL1/GAL10 promoter and the AAE1 gene under the regulation of the STE5 promoter. The bCBGA0409 vector (SEQ ID NO: 36) contained the Saccharomyces cerevisiae 2μ replication origin, the LEU2 gene as an auxotrophic marker, the THCA synthase and PT genes under the regulation of the bidirectional GAL1/GAL10 promoter.
The yCBGA0251 strain was constructed by inserting the ERG20mut-dPT gene under the regulation of the bidirectional GAL1/GAL10 promoter into the YMR145C locus by replacing the native YMR145C ORF of the yCBGA0237 strain. The yCBGA0269 strain was constructed by deleting a 133 nucleotide long fragment between 143 and 275 nucleotides upstream of the translational start site of the native ERG20 allele of the yCBGA0251 strain. Plasmids RUNM001210_96.1 and bCBGA0409 were transformed into the yCBGA0269 strain by electroporation. Transformants were selected by their uracil and leucine prototrophy on SD/MSG minimal medium supplemented with histidine and tryptophan.
Transformant colonies were picked and inoculated into separate wells of a 96-well deep well plate. Each well contained 400 μl SC-URA-LEU (6.7 g/L Yeast Nitrogen Base, 1.6 g/L Amino Acid Drop Out mix without uracil and leucine, 22 g/L glucose, buffered to pH 6.0). These inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter. After the 48 hours growth period 40 μl samples of these cultures were inoculated into 360 μl YPD-HXA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 100 mg/L hexanoic acid) medium. Then samples were grown for 16 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 40 μg hexanoic acid dissolved in 8 μl ethanol was added to the samples. Finally, samples were grown for additional 32 hours and were analyzed for THCA and CBGA titers as described below.
Using the strains and methods described above CBGA was produced at 34 mg/L concentration while THCA was produced at 23 mg/L concentration.
The samples from examples 8 and 9 were processed by dilution with acetonitrile:water mixture (the composition of the mixture depends on the dilution factor, to reach 50% acetonitrile content for further processing), then shaken for 5 minutes at 30° C. at 300 rpm with 50 mm throw. The samples were then centrifuged at 400 rpm for 5 minutes. 200 μl of supernatant were transferred into a new 96 well plate.
The new 96 well plate were transferred to a Waters Acquity UPLC (Binary pump)-TQD MS and set with the following parameters:
Representative chromatograms of a THCA containing sample can be seen in
Increased Prenyl Transferase copy number and promoter truncation improves prenyl transferase activity. The yCBGA0314 strain was constructed and tested for the effect of PT copy number on CBGA production. The yCBGA0314 strain was constructed by inserting the ERG20mut-dPT gene under the regulation of the bidirectional GAL1/GAL10 promoter into the LPP1 locus by replacing the native LPP1 ORF of the yCBGA0269 strain. The yCBGA0314 strain and several other previously described strains are listed in Table 3 below along with their respective gene insertions/mutations:
Transformant colonies were grown using the following protocol: Transformant colonies were inoculated into wells of a 96-well deep well plate. Each well contained 400 μl SC Medium (6.7 g/L Yeast Nitrogen Base, 1.6 g/L Amino Acid Drop Out mix without leucine, uracil, tryptophan and histidine, 22 g/L glucose, buffered to pH 6.0, supplemented with leucine, uracil, tryptophan and histidine). These inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter. After the 48 hours growth period, 40 μl samples of these cultures were inoculated into 360 μl YPD-2400LA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 240 mg/L olivetolic acid) medium. Then samples were grown for 24 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 8 μl of 12000 mg/L OLA dissolved in EtOH was added to the samples. Finally, the samples were grown for additional 24 hours and were analyzed for cannabinoids.
The yCBGA0314 strain produced 450 mg/L CBGA using 480 mg/L olivetolic acid as substrate.
Cannabinoid production can be limited by the availability of hexanoic acid. We tested to see if the availability of hexanoic acid can be increased by knocking out several genes of the beta-oxidation pathway. In particular, we tested to see if hexanoic acid degradation could be prevented or minimized. Deletion of FAA1, FAA4, FAT1, PXA1, PXA2 and PEX11 had no obvious effect on hexanoic acid titers: after 24 hours of growth in YPD-HXA medium the hexanoic acid concentration was dropped below 5% of the original level (no heterologous cannabinoid pathway genes present). In other words, hexanoic degradation was not affected. A wild type control strain performed similarly, resulting in less than 5% final hexanoic acid concentration. However, deletion of the FOX1 gene (a.k.a. PDX1, systematic name YGL205W) increased hexanoic acid titers. The knockout of FOX1 eliminated HXA degradation almost completely: 95% of the original hexanoic concentration was still present at the end of the 24 hour long growth period.
Yeast strains having the ability to make CBGA were also knocked out for the FOX1 gene. yCBGA0326 strain was constructed by first, inserting the PKS and OAC genes under the regulation of the bidirectional GAL1/GAL10 promoter and the AAE1 gene under the regulation of the HXK1 promoter into the YGL202W locus replacing the native YGL202W ORF, second, inserting the PKS and OAC genes under the regulation of the bidirectional GAL1/GAL10 promoter and the AAE1 gene under the regulation of the HXK1 promoter into the DPP1 locus replacing the native DPP1 ORF, third, inserting the PKS and OAC genes under the regulation of the bidirectional GAL1/GAL10 promoter into the BTS1 locus replacing the native BTS1 ORF. yCBGA0373 strain was constructed by deleting the FOX1 gene, more specifically the nucleotide fragment between −73 and 3243 relative to the translational start site.
Strains yCBGA0326 and yCBGA0373 were inoculated into separate wells of a 96-well deep well plate. Each well contained 400 μl Synthetic Complete (SC) liquid medium (6.7 g/L Yeast Nitrogen Base, 1.6 g/L Amino Acid Drop Out mix without uracil and leucine, 22 g/L glucose, buffered to pH 6.0, supplemented with leucine and uracil). These inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter. After the 48 hours growth period 40 μl samples of these cultures were inoculated into 360 μl YPD-50HXA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 50 mg/L hexanoic acid) medium. Then samples were grown for 24 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter, then 20 μg hexanoic acid dissolved in 8 μl ethanol was added to the samples. Finally, samples were grown for additional 24 hours and four replicates of both strains were analyzed for CBGA titers.
Using the methods described above, CBGA, olivetol, and olivetol acid titers were measured. As seen in
Increasing the copy number of genes required for olivetolic acid production increased the corresponding CBGA titer. The yCBGA0268 strain was constructed by replacing the native YGL202W ORF of the yCBGA0251 strain by inserting the PKS and OAC genes under the regulation of the bidirectional GAL1/GAL10 promoter and the AAE1 gene under the regulation of the HXK1 promoter into the YGL202W locus. The yCBGA0268 strain and several other previously described strains are listed below along with their respective gene insertions/mutations. The Table 4 illustrates how copy number of the olivetolic acid biosynthetic genes increases the final CBGA titer.
The yCBGA0513 strain, a strain containing multiple copies of prenyl transferase and genes required for olivetolic acid production, was constructed. The strain produced increased levels of CBGA using hexanoic acid as its substrate. For the strain construction, the parental strain was the yCBGA0314 strain which contained 3 copies of GFP-dPT and/or ERGOmut-dPT genes in total among other host modifications as described above. Three copies of the PKS and OAC genes under the regulation of the bidirectional GAL1/GAL10 promoter and three copies of the AAE1 gene under the regulation of the STE5 promoter were inserted into the YDR508C, YRL020C and FOX1 loci replacing the native ORFs of the yCBGA0314 strain. A large number of isolates from this transformation were screened and an isolate with high CBGA productivity and the best reproducibility was identified. Next, to complement the auxotrophic mutations of this strain, URA3, HISS LEU2 and TRP1 genes on a single fragment were inserted 3′ of the genomic ARG2 locus, resulting in the final yCBGA0513 strain.
Colonies were inoculated into wells of a 96-well deep well plate. Each well contained 400 μl SC (6.7 g/L Yeast Nitrogen Base, 1.6 g/L Amino Acid Drop Out mix without leucine, uracil, tryptophan and histidine, 22 g/L glucose, buffered to pH 6.0, supplemented with leucine, uracil, tryptophan and histidine). These inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter. After the 48 hours growth period 40 μl samples of these cultures were inoculated into 360 μl YPD-HXA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 100 mg/L hexanoic acid) medium. Then samples were grown for 24 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 40 μg hexanoic acid dissolved in 8 μl ethanol was added to the samples. Finally, the samples were grown for additional 24 hours and were analyzed for cannabinoids.
The yCBGA0513 strain was able to produce 140 mg/L CBGA in a standard high throughput screen. 1) The high prenyl transferase activity and optimized GPP productivity, as described for the parental yBGA0314 strain, 2) the replacement of the FOX1 gene that minimizes the degradation of hexanoic acid, and 3) and/or the integration of more than 3 copies of the genes required for olivetolic acid synthesis likely contribute to the high CBGA productivity.
To further test the potential of the yCBGA0513 strain, it was challenged in a modified screening procedure. yCBGA0513 strain was inoculated into wells of a 96-well deep well plate. Each well contained 400 μl SC liquid medium (6.7 g/L Yeast Nitrogen Base, 1.6 g/L Amino Acid Drop Out mix without leucine, uracil, tryptophan and histidine, 22 g/L glucose, buffered to pH 6.0, supplemented with leucine, uracil, tryptophan and histidine). These inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter. After the 48 hours growth period 40 μl samples of these cultures were inoculated into 360 μl YPD-HXA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 100 mg/L hexanoic acid) medium. Then samples were grown for 96 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 40 μg hexanoic acid dissolved in 8 μl ethanol was added to the samples at two time-points: at 24 and 48 hour. At the end of the 96 hour growth period, the samples were analyzed for cannabinoids. The yCBGA0513 strain produced 300 mg/L CBGA using hexanoic acid as substrate.
Several additional strains containing multiple copies of prenyl transferase and genes required for olivetolic acid production were constructed utilizing yCBGA0513 as the parent strain. The yCBGA0520, yCBGA0523 and yCBGA0526 strains are able to produce high levels of CBGA using hexanoic acid as substrate. The yCBGA0520 strain was constructed by inserting the ERG13 gene (encoding Hydroxymethylglutaryl-CoA synthase) under the regulation of the ADH2 promoter, the HMG1 gene (encoding Hydroxymethylglutaryl-CoA reductase) under the regulation of the TEF1 promoter, and the ERG20mut-dPT gene with a TPI1 terminator under the regulation of the HXK1 promoter into the ATG26 locus by replacing the native ATG26 ORF of the yCBGA0513 strain. The yCBGA_0523 strain was constructed by inserting the tHMG1 gene under the regulation of the ADH2 promoter, the ERG10 gene (encoding Acetyl-CoA C-acetyltransferase) under the regulation of the TEF1 promoter, and the ERG13 gene under the regulation of the HXK1 promoter into the ATG26 locus by replacing the native ATG26 locus of the yCBGA0513 strain. The yCBGA_0526 strain was constructed by inserting the tHMG1 gene under the regulation of the ADH2 promoter, the ERG13 gene under the regulation of the TEF1 promoter, and the AAE1 gene with a TEF1 terminator under the regulation of the HXK1 promoter into the ATG26 locus by replacing the native ATG26 ORF of the yCBGA0513 strain. tHMG1 stands for the Saccharomyces cerevisiae HMG1 gene truncated of the first 530 amino acids. ERG10, ERG13, HMG1 and tHMG1 gene cassettes contain their native terminator sequences. ERG20mut-dPT and AAE1 were described earlier. The ATG26 locus of the yCBGA0513 strain and the corresponding locuses in the yCBGA0520 strain, the yCBGA0523 strain, and the yCBGA0526 strain which replaced the ATG26 locus are disclosed in
The strains and their gene insertions are listed in Table 5 below:
tHMG1 stands for the Saccharomyces cerevisiae HMG1 gene truncated of the first 530 amino acids. ERG10, ERG13, HMG1 and tHMG1 gene cassettes contain their native terminator sequences. ERG20mut-dPT and AAE1 were described earlier.
All 3 strains outperformed the yCBGA0513 strain in the following modified high throughput screen: Colonies were inoculated into wells of a 96-well deep well plate. Each well contains 400 μl Synthetic Complete Medium (6.7 g/L Yeast Nitrogen Base, 1.6 g/L Amino Acid Drop Out mix without leucine, uracil, tryptophan and histidine, 22 g/L glucose, buffered to pH 6.0, supplemented with leucine, uracil, tryptophan and histidine). These inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter. After the 48 hours growth period, 40 μl samples of these cultures were inoculated into 360 μl YPD-HXA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 100 mg/L hexanoic acid) medium. Then samples were grown for 72 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 80 μg hexanoic acid dissolved in 8 μl ethanol was added to the samples at two time-points: at 24 and 48 hours. At the end of the 72 hour growth period, the samples were analyzed for cannabinoids. The strains and their final olivetolic acid, olivetol and CBGA titers are listed in Table 6 below:
To improve the performance of TKS, an enzyme evolution experiment was conducted. The wild type amino acid and nucleotide sequences of Saccharomyces cerevisiae TKS are included Table 7 below:
Each position in TKS listed in Table 8 below was mutagenized and 20-100 yeast colonies carrying randomly changed amino acids for each marked positions were screened for elevated performance.
The amino acid position A1a125, coding for Alanine in the wild type sequence was found to be able to elevate the TKS activity when the Alanine was swapped for different amino acids. When this amino acid position of TKS contained Serine, the corresponding olivetolic acid production was 50 mg/L in contrast with the 37 mg/L measured in case of the wild type TKS gene.
The TKS gene was inserted into a plasmid containing the Saccharomyces cerevisiae 2μ replication origin, the URA3 gene as an auxotrophic marker and the TKS gene under the regulation of the GAL10 promoter. The plasmid ID of the control plasmid with wild type TKS sequence was bCBGA1024. The ID of the plasmid with the Alanine to Serine mutation at position 125 is 0827-01-A1-1 (
The yCBGA0368 strain was used for screening these mutant plasmids. yCBGA0368 was constructed by inserting the AAE1 gene under the regulation of the STE5 promoter and the OAC gene under the regulation of the GAL1 promoter into the YKL140W locus by replacing the native YMR145C ORF of the yCBGA0215 strain (
The secretion of CBDAs was optimized to be able produce large amounts of CBDA in a single process using yeast cells, the wild type sequences for the Saccharomyces cerevisiae CBDA amino acid and nucleotide sequences are included in Table 9:
A series of plasmids were constructed containing the Saccharomyces cerevisiae replication origin, the URA3 gene as an auxotrophic marker and the CBDA synthase gene under the regulation of the bidirectional GAL1/GAL10 promoter. In each plasmid, the predicted plant secretion signal corresponding to the first 21 amino acid of the CBDA synthase was replaced with different yeast secretion signals, see table below.
This set of plasmids were separately transformed into yCBGA0314 strains and their CBDA productivity was assayed in a high throughput screening process optimized for CBDA synthase activity. The nucleotide sequences and protein sequence of the tested signal sequences are included in Tables 10-11 below, along with the plasmid IDs, the corresponding amino acid sequences, the ORF names and CBDA titer.
A high throughput screening process of the CBDAs synthase activity was conducted as follows: Colonies were inoculated into wells of a 96-well deep well plate. Each well contained 400 μl SC liquid medium (6.7 g/L Yeast Nitrogen Base, 1.6 g/L Amino Acid Drop Out mix without leucine, uracil, tryptophan and histidine, 22 g/L glucose, buffered to pH 6.0, supplemented with leucine, tryptophan and histidine). These inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter. After the 48 hours growth period 40 μl samples of these cultures were inoculated into 360 μl YPD-2400LA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 240 mg/L olivetolic acid) medium. Then samples were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 8 μl of 12000 mg/l OLA dissolved in EtOH is added to the samples. Finally, samples were grown for additional 42 hours and are analyzed for cannabinoids. The CBDA titer in the above described screen ranged from 7 to 285 mg/L. For details, see the Table 12 below. (The titers are also included in Table 10 above.)
Proteomic analysis using the methods described in Example 4 confirmed that the most active sample had an elevated CBDA synthase concentration in the culture supernatant, most probably due to more effective CBDA synthase secretion. CBDA synthase supernatant concentration was over 15-fold more in strains transformed with the bCBGA1854 plasmid (SEQ ID No: 435), than strains transformed with RUNM001233_67.1. (The corresponding CBDA titers are 285 mg/L and 124 mg/L, respectively.) That is, CBDA productivity and secretion can be increased by improving CBDA synthase secretion.
The supernatant of the culture transformed with the bCBGA1854 plasmid was mixed with 100 mg/L CBGA, and after 48 hours of incubation, 30 mg/L CBDA was detected, proving that there is active CBDA synthase in the supernatant of the yeast culture.
The secretion of CBDAs was further optimized. A second series of plasmids were constructed containing the Saccharomyces cerevisiae 2μ replication origin, the URA3 gene as an auxotrophic marker and the CBDA synthase gene under the regulation of the bidirectional GAL1/GAL10 promoter. The first 21, or in some cases 28, amino acids of the CBDA synthase in each plasmid was replaced with different yeast secretion signals. The secretion signals included various combinations of the K28 viral secretion signal, the N-terminal 233 amino acid of the PIR3 protein, denoted as PIR3 delta fragment (with or without its predicted native secretion signal), a Kex2p cleavage site and a short spacer motif. The nucleotide sequences and protein sequences of the tested signal sequences are included in Tables 13-14 below, along with the plasmid IDs, the corresponding amino acid sequences, the ORF names and CBDA titer.
This set of plasmids were each individually transformed into the yCBGA0314 strain and their CBDA productivity was assayed in a high throughput screening process optimized for CBDAs synthase activity as described in Example 17 above. The CBDA titer in the above described screen reached up to 381 mg/L. Samples titers for several transformed strains are included in Table 15 below. (The titers are also included in Table 13 above.)
CBDA productivity was further improved by deletions in the VPS10 gene of the host. Two deletions were made: yCBGA0508 strain was constructed by deleting the whole coding sequence of the VPS locus of the yCBGA0314 strain. yCBGA0509 strain was made by deleting the majority of the 5′ half of the coding sequence of the VPS locus of the yCBGA0314 strain. (
The bCBGA1854 plasmid was transformed into the strains yCBGA0314, yCBGA0508 and yCBGA0509 and their CBDA producing capacity was assayed in an improved CBDA screening process.
Improved high throughput screening process of the CBDAs synthase activity.
Colonies were inoculated into wells of a 96-well deep well plate. Each well contained 400 μl SC liquid medium (6.7 g/L Yeast Nitrogen Base, 1.6 g/L Amino Acid Drop Out mix without leucine, uracil, tryptophan and histidine, 22 g/L glucose, buffered to pH 6.0, supplemented with leucine, tryptophan and histidine). These inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter. After the 48 hours growth period 40 μl samples of these cultures were inoculated into 360 μl YPD-pH6-2400LA (10 g/L yeast extract (Ohly), 20 g/L soy peptone (Organotechnie), 20 g/L glucose, buffered to pH6 with sodium phosphate, 240 mg/L olivetolic acid) medium. Then samples were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 8 μl of 12000 mg/l OLA dissolved in EtOH is added to the samples. Finally, samples were grown for additional 48 hours and are analyzed for cannabinoids.
In this screen, the following CBDA titers were detected: see Table 16 below. Both types of deletion in the VPS10 gene had a positive effect on CBDA productivity.
CBDA production from a hexanoic acid substrate was tested using the yCBGA0499 strain, which contains the bCBAG1854 plasmid described in Example 19 above.
For the strain construction the parental strain was the yCBGA0314 strain. The PKS and OAC genes under the regulation of the bidirectional GAL1/GAL10 promoter and the AAE1 gene under the regulation of the STE5 promoter were inserted into the YDR508C, YRL020C and FOX1 loci replacing the native ORFs of the yCBGA0314 strain. The PKS and OAC genes (under the regulation of the bidirectional GAL1/GAL10 promoter) and the AAE1 gene (under the regulation of the STE5 promoter) were inserted into the YDR508C locus. A second copy of the PKS and OAC genes (under the regulation of the sa promoter) and the AAE1 gene (under the regulation of the STE5 promoter) were inserted into the YRL020C locus. A third copy of the PKS and OAC genes (under the regulation of the bidirectional GAL1/GAL10 promoter) and the AAE1 gene (under the regulation of the STE5 promoter) were inserted into the FOX1 locus. A large number of isolates from this transformation were screened and an isolate with high CBGA productivity was identified as yCBGA0499.
The yCBGA0499 with bCBGA1854 plasmid was assayed for CBDA productivity using the following high throughput screening process using hexanoic acid for CBDA production. Colonies were inoculated into wells of a 96-well deep well plate. Each well contained 400 μl Synthetic Complete liquid medium (6.7 g/L Yeast Nitrogen Base, 1.6 g/L Amino Acid Drop Out mix without leucine, uracil, tryptophan and histidine, 22 g/L glucose, buffered to pH 6.0, supplemented with leucine, tryptophan and histidine). These inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter. After the 48 hours growth period, 40 μl samples of these cultures were inoculated into 360 μl YPD-pH6-HXA (10 g/L yeast extract (Ohly), 20 g/L soy peptone (Organotechnie), 20 g/L glucose, buffered to pH6 with sodium phosphate, 100 mg/L hexanoic acid) medium. Then samples were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 40 μg hexanoic acid dissolved in 8 μl ethanol is added to the samples. Finally, the samples were grown for additional 48 hours and were analyzed for cannabinoids.
Using this screening method, the yCBGA0499 strain produced 51 mg/L CBDA in one single biological process using hexanoic acid as substrate.
To produce a stable prototrophic strain for CBDA production, the yCBGA0519 strain was constructed by inserting a modified CBDA synthase gene, denoted as PIR3-CBDAs, into the yCBGA0513 strain:
For the strain construction, the parental strain was the prototrophic CBGA producer yCBGA0513 strain. The gene coding for the PIR3-CBDAs under the regulation of the bidirectional GAL1/GAL10 promoter was integrated into the YKL140W locus by replacing the native YKL140W ORF of the yCBGA0513 strain. The amino acid sequence of PIR3-CBDAs consists of the N-terminal 233 amino acid of the PIR3 protein, the LEKREAEA peptide motif (SEQ ID NO: 118) as a Kex2p cleavage site, and the CBDA synthase coding sequence lacking its first 21 amino acids. The nucleotide sequence of PIR3-CBDAs is SEQ ID NO: 301. The amino acid sequence of PIR3-CBDAs is SEQ ID NO: 302.
The yCBGA0519 strain was assayed for CBDA productivity using a modified high throughput screening process using hexanoic acid for CBDA production described in Example 20 above. The yCBGA0519 strain produced 144 mg/L CBDA in one single biological process using hexanoic acid as substrate.
The secretion of THCAs was optimized to be able produce large amount of THCA in a single process using yeast cells. The wild type sequences for the Saccharomyces cerevisiae THCA synthase amino acid and nucleotide sequences are included in Table 17:
A series of plasmids were constructed containing the Saccharomyces cerevisiae replication origin, the URA3 gene as an auxotrophic marker and the THCA synthase gene under the regulation of the bidirectional GAL1/GAL10 promoter. In each plasmid various yeast secretion signals were used, in some cases the first 28 amino acids of the THCA synthase protein predicted to be a plant secretion signal was removed. The nucleotide sequences and protein sequences of the tested signal sequences are included in Tables 18-19 below, along with the plasmid IDs, the corresponding amino acid sequences, the ORF names and THCA titer.
This set of plasmids was transformed into the yCBGA0314 strain and their CBDA productivity was assayed in the following high throughput screening process optimized for the CBDAs synthase activity. Colonies were inoculated into wells of a 96-well deep well plate. Each well contains 400 μl SC liquid medium (6.7 g/L Yeast Nitrogen Base, 1.6 g/L Amino Acid Drop Out mix without leucine, uracil, tryptophan and histidine, 22 g/L glucose, buffered to pH 6.0, supplemented with leucine, tryptophan and histidine). These inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter. After the 48 hours growth period 40 μl samples of these cultures were inoculated into 360 μl YPD-2400LA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 240 mg/L olivetolic acid) medium. Then samples were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 8 μl of 12000 mg/l OLA dissolved in EtOH is added to the samples. Finally, samples were grown for additional 42 hours and are analyzed for cannabinoids.
The THCA titer in the above described screen ranged from 4 to 512 mg/L. Sample titers for several transformed strains are included in Table 20 below. (The titers are also included in Table 18 above.)
One amino acid position was mutagenized in the THCA synthase. The mutant genes were screened in yeast. Clones with increased THCA titer were identified.
The parental plasmid for the mutagenesis was the RUNM001233_63.1 plasmid, containing the Saccharomyces cerevisiae 2μ replication origin, the URA3 gene as an auxotrophic marker and a modified THCA synthase gene under the regulation of the bidirectional GAL1/GAL10 promoter. The nucleotide sequence of RUNM001233_63.1 is SEQ ID NO: 303. The modified THCA synthase gene contained a chimeric secretion signal and the THCA synthase gene lacking its predicted 28 amino acid long plant secretion signal.
The mutagenized position is the 469th amino acid position of this modified THCA synthase protein, corresponding to the 446th amino acid position of the unmodified THCA synthase protein. This position contains threonine in the natural THCA synthase. We have constructed large number of plasmids where the above-mentioned codon was randomly mutated allowing the incorporation of codons of any of the 20 amino acids.
The RUNM001233_63.1 plasmid and large number of its mutagenized variants were transformed into the yCBGA0517 strain and screened for THCA production. For the strain construction the parental strain was the yCBGA0314 strain. The PKS and OAC genes under the regulation of the bidirectional GAL1/GAL10 promoter and the AAE1 gene under the regulation of the STE5 promoter were inserted into the YDR508C, YRL020C and FOX1 loci replacing the native ORFs of the yCBGA0314 strain. A large number of isolates from this transformation was screened and few of them with high CBGA productivity and best reproducibility were identified. One of these isolates was prototrophic for uracil. Next, its URA3 gene was swapped with HIS3 gene resulting in the strain yCBGA0517, prototrophic for histidine and auxotrophic for uracil, leucine and tryptophan.
Colonies were screened using the following high throughput screening process of the THCA synthase activity: Colonies were inoculated into wells of a 96-well deep well plate. Each well contains 400 μl Synthetic Complete liquid medium (6.7 g/L Yeast Nitrogen Base, 1.6 g/L Amino Acid Drop Out mix without leucine, uracil, tryptophan and histidine, 22 g/L glucose, buffered to pH 6.0, supplemented with leucine, tryptophan and histidine). These inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter. After the 48 hours growth period 40 μl samples of these cultures are inoculated into 360 μl YPD-2400LA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 240 mg/L olivetolic acid) medium. Then samples are grown for 48 hours at 30° C. and shaken at 300 rpm with a 50 mm shaking diameter and 8 μl of 12000 mg/l OLA dissolved in EtOH is added to the samples. Finally, samples were grown for additional 42 hours and are analyzed for cannabinoids.
The plasmid sequence of the best producer clones was determined. In all cases, the plasmids contained mutations only in the region of the mutagenized codon.
When Alanine, Valine or Isoleucine is coded for in the above-mentioned position of the modified THCA synthase gene, increased THCA titer was observed, as summarized in the Table 21 below:
Eighty-four (84) amino acid positions in the native Cannabis sativa CBDA synthase gene were mutagenized. The mutant genes were screened in yeast. Clones were identified with increased CBDA titer.
The parental plasmid for the mutagenesis was the 0285/asn080-2 plasmid, containing the Saccharomyces cerevisiae 2μ replication origin, the Hygromycin B resistance gene as a dominant marker and one of the modified CBDA synthase genes disclosed in this example under the regulation of the bidirectional GAL1/GAL10 promoter. The modified CBDA synthase gene contained the PIR3 delta fragment as secretion signal and the CBDA synthase gene lacking its predicted 21 amino acid long plant secretion signal. The modified CBDA coding sequences used for the 0285/asn080-2 parental plasmid are included in Table 22 below.
The eighty-four (84) amino acid positions encoded by the wild-type CBDA synthase gene were selected for mutagenesis based on the fact that they contained amino acid differences with THCA synthase when aligned sequentially. The wild-type CBDA synthase specific amino acid was replaced at each of these positions for the corresponding amino acid found in the THCA synthase protein. 0285/asn080-2 plasmids containing the mutants were transformed into the yCBGA0513 strain and screened for CBDA production.
Several double combinations of these mutations were also introduced into the 0285/asn080-2 plasmid, and along with their corresponding single mutant plasmid counterparts, were transformed into the yCBGA0523 strain and screened for CBDA production.
The CBDA mutant (and wild type) coding sequences used for the 0285/asn080-2 parental plasmid are included in Table 22 in Example 24.
CBDA synthase activity in the strains was screened using the following high throughput screening process. Colonies were inoculated into wells of a 96-well deep well plate. Each well contained 400 μl SC liquid medium (6.7 g/L Yeast Nitrogen Base, 1.6 g/L Amino Acid Drop Out mix without leucine, uracil, tryptophan and histidine, 22 g/L glucose, buffered to pH 6.0, supplemented with leucine, tryptophan, histidine and Hygromycin B). These inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with 50 mm shaking diameter. After a 48 hour growth period, 40 μl samples of these cultures were inoculated into 360 μl YPD-2400LA (10 g/L yeast extract, 20 g/L peptone, 20 g/L glucose and 240 mg/L olivetolic acid) medium. Then samples were grown for 48 hours at 30° C. and shaken at 300 rpm with 50 mm shaking diameter and 8 μl of 12000 mg/l OLA dissolved in EtOH is added to the samples. Finally, samples were grown for additional 42 hours and were analyzed for cannabinoids.
The CBDA titer in the above described screen ranged from 10.5 to 408.6 mg/L. Sample titers for the transformed strains, along with each strain's respective amino acid mutations and amino acid sequences, are included in Tables 23-26 below. (All mutation sites refer to the mutation site on wild-type CBDA's coding sequence without the wild-type signal sequence.)
Fifty-three (53) positions around the predicted active site of the Cannabis sativa native CBDA synthase enzyme were mutagenized in a random manner to increase the synthesis of CBCA. The parental plasmid for mutagenesis was the 0285/asn080-2 plasmid. Plasmids carrying mutant CBDA synthase genes were isolated and screened for CBCA synthase activity. The screen identified amino acid positions where substitutions for certain amino acids result in the formation of a highly specific CBCA synthase or CBDA synthase with elevated CBCA synthase activity. The parental plasmid and plasmids with mutant CBDA synthase gene were transformed into the yCBGA0513 strain.
Mutant CBDA synthases with CBCA activity were screened using the following high throughput screening process: Colonies were inoculated into wells of a 96-well deep well plate.

The inoculums were grown for 48 hours at 30° C. and shaken at 300 rpm with 50 mm shaking diameter.

Then samples were grown for 48 hours at 30° C. and shaken at 300 rpm with 50 mm shaking diameter and 8 μl of 12000 mg/l OLA dissolved in EtOH was added to the samples. Finally, samples were grown for an additional 42 hours and were analyzed for cannabinoids.
The CBCA titer in the above described screen ranged from 18.0 to 69.6 mg/L. Sample titers for the transformed strains, along with each strain's respective amino acid mutations and amino acid sequences, are included in Tables 27-28 below. (All mutation sites refer to the mutation site on CBDA's coding sequence without the wild-type signal sequence.)
To improve the performance of CBCA synthase, an enzyme mutagenesis experiment was conducted. The mutant CBCA C-terminal core enzyme contains 3 differences as the compared to CBDA Cannabis sativa C-terminal core enzyme, G74A, S insertion at 232, and M269T (when numbering the core sequence (without the signal sequence).

To improve the performance of prenyl transferase (PT), a site directed mutagenesis experiment was conducted. The base gene for mutagenesis was a fusion construct: N-terminal part: yEVenus (a modified GFP protein); C-terminal part: GFP-dPT of strain 314 (SEQ ID NO: 27), a truncated Saccharomyces cerevisiae prenyl-transferase (the N-terminal 98 amino acid of the original prenyl-transferase was truncated), and the sequences are included Table 31 below:
