The quest for an optimal xylose pathway in yeast is of utmost importance along the way to realizing the potential of lignocellulosic biomass conversion into fuels and chemicals. An often overlooked aspect of this catabolic pathway is the molecular transport of this sugar. Molecular transporter proteins facilitate monosaccharide uptake and serve as the first step in catabolic metabolism. In this capacity, the preferences, regulation, and kinetics of these transporters ultimately dictate total carbon flux (1-3); and optimization of intracellular catabolic pathways only increases the degree to which transport exerts control over metabolic flux (4, 5). Thus, monosaccharide transport profiles and rates are important design criteria and a driving force to enable metabolic engineering advances (6-10). Furthermore, the presence of other hexose sugars, such as glucose, can hamper efficient transport of xylose by inhibiting sugar transporters. There is a need in the art for efficient transport systems for xylose in yeast when glucose is present. Provided herein are solutions to these and other problems in the art.

Unless defined otherwise, all technical and scientific terms used herein generally have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Generally, the nomenclature used herein and the laboratory procedures in cell culture, molecular genetics, organic chemistry, and nucleic acid chemistry and hybridization described below are those well-known and commonly employed in the art. Standard techniques are used for nucleic acid and peptide synthesis. The techniques and procedures are generally performed according to conventional methods in the art and various general references (see generally, Sambrook et al. MOLECULAR CLONING: A LABORATORY MANUAL, 2d ed. (1989) Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., which is incorporated herein by reference), which are provided throughout this document.
“Nucleic acid” refers to deoxyribonucleotides or ribonucleotides and polymers thereof in either single- or double-stranded form, and complements thereof. The term “polynucleotide” refers to a linear sequence of nucleotides. The term “nucleotide” typically refers to a single unit of a polynucleotide, i.e., a monomer. Nucleotides can be ribonucleotides, deoxyribonucleotides, or modified versions thereof. Examples of polynucleotides contemplated herein include single and double stranded DNA, single and double stranded RNA (including siRNA), and hybrid molecules having mixtures of single and double stranded DNA and RNA. Nucleic acid as used herein also refers nucleic acids that have the same basic chemical structure as a naturally occurring nucleic acids. Such analogues have modified sugars and/or modified ring substituents, but retain the same basic chemical structure as the naturally occurring nucleic acid. A nucleic acid mimetic refers to chemical compounds that have a structure that is different the general chemical structure of a nucleic acid, but that functions in a manner similar to a naturally occurring nucleic acid. Examples of such analogues include, without limitation, phosphorothiolates, phosphoramidates, methyl phosphonates, chiral-methyl phosphonates, 2-O-methyl ribonucleotides, and peptide-nucleic acids (PNAs).
“Synthetic mRNA” as used herein refers to any mRNA derived through non-natural means such as standard oligonucleotide synthesis techniques or cloning techniques. Such mRNA may also include non-proteinogenic derivatives of naturally occurring nucleotides. Additionally, “synthetic mRNA” herein also includes mRNA that has been expressed through recombinant techniques or exogenously, using any expression vehicle, including but not limited to prokaryotic cells, eukaryotic cell lines, and viral methods. “Synthetic mRNA” includes such mRNA that has been purified or otherwise obtained from an expression vehicle or system.
The words “complementary” or “complementarity” refer to the ability of a nucleic acid in a polynucleotide to form a base pair with another nucleic acid in a second polynucleotide. For example, the sequence A-G-T is complementary to the sequence T-C-A. Complementarity may be partial, in which only some of the nucleic acids match according to base pairing, or complete, where all the nucleic acids match according to base pairing.
Nucleic acid is “operably linked” when it is placed into a functional relationship with another nucleic acid sequence. For example, DNA for a presequence or secretory leader is operably linked to DNA for a polypeptide if it is expressed as a preprotein that participates in the secretion of the polypeptide; a promoter or enhancer is operably linked to a coding sequence if it affects the transcription of the sequence; or a ribosome binding site is operably linked to a coding 15 sequence if it is positioned so as to facilitate translation. Generally, “operably linked” means that the DNA sequences being linked are near each other, and, in the case of a secretory leader, contiguous and in reading phase.
The terms “polypeptide,” “peptide” and “protein” are used interchangeably herein to refer to a polymer of amino acid residues. The terms apply to amino acid polymers in which one or more amino acid residue is an artificial chemical mimetic of a corresponding naturally occurring amino acid, as well as to naturally occurring amino acid polymers and non-naturally occurring amino acid polymer.
The term “amino acid” refers to naturally occurring and synthetic amino acids, as well as amino acid analogs and amino acid mimetics that function in a manner similar to the naturally occurring amino acids. Naturally occurring amino acids are those encoded by the genetic code, as well as those amino acids that are later modified, e.g., hydroxyproline, γ-carboxyglutamate, and O-phosphoserine. Amino acid analogs refers to compounds that have the same basic chemical structure as a naturally occurring amino acid, i.e., an α carbon that is bound to a hydrogen, a carboxyl group, an amino group, and an R group, e.g., homoserine, norleucine, methionine sulfoxide, methionine methyl sulfonium. Such analogs have modified R groups (e.g., norleucine) or modified peptide backbones, but retain the same basic chemical structure as a naturally occurring amino acid. Amino acid mimetics refers to chemical compounds that have a structure that is different from the general chemical structure of an amino acid, but that functions in a manner similar to a naturally occurring amino acid.
Amino acids may be referred to herein by either their commonly known three letter symbols or by the one-letter symbols recommended by the IUPAC-IUB Biochemical Nomenclature Commission. Nucleotides, likewise, may be referred to by their commonly accepted single-letter codes.
A “conservative substitution” as used with respect to amino acids, refers to the substitution of an amino acid with a chemically similar amino acid. Amino acid substitutions which often preserve the structural and/or functional properties of the polypeptide in which the substitution is made are known in the art and are described, for example, by H. Neurath and R. L. Hill, 1979, in “The Proteins,” Academic Press, New York. The most commonly occurring exchanges are isoleucine/valine, tyrosine/phenylalanine, aspartic acid/glutamic acid, lysine/arginine, methionine/leucine, aspartic acid/asparagine, glutamic acid/glutamine, leucine/isoleucine, methionine/isoleucine, threonine/serine, tryptophan/phenylalanine, tyrosine/histidine, tyrosine/tryptophan, glutamine/arginine, histidine/asparagine, histidine/glutamine, lysine/asparagine, lysine/glutamine, lysine/glutamic acid, phenylalanine/leucine, phenylalanine/methionine, serine/alanine, serine/asparagine, valine/leucine, and valine/methionine. The following eight groups each contain amino acids that are conservative substitutions for one another: 1) Alanine (A), Glycine (G); 2) Aspartic acid (D), Glutamic acid (E); 3) Asparagine (N), Glutamine (Q); 4) Arginine (R), Lysine (K); 5) Isoleucine (I), Leucine (L), Methionine (M), Valine (V); 6) Phenylalanine (F), Tyrosine (Y), Tryptophan (W); 7) Serine (S), Threonine (T); and 8) Cysteine (C), Methionine (M) (see, e.g., Creighton, Proteins (1984)). In some embodiments, there may be at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 15, at least 20, at least 25, at least 30, at least 35, or at least 40 conservative substitutions. In some embodiments, there may be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, or 40 conservative substitutions.
As to amino acid sequences, one of skill will recognize that individual substitutions, deletions or additions to a nucleic acid, peptide, polypeptide, or protein sequence which alters, adds or deletes a single amino acid or a small percentage of amino acids in the encoded sequence is a “conservatively modified variant” where the alteration results in the substitution of an amino acid with a chemically similar amino acid. Conservative substitution tables providing functionally similar amino acids are well known in the art. Such conservatively modified variants are in addition to and do not exclude polymorphic variants, interspecies homologs, and alleles of the invention.
An amino acid or nucleotide base “position” is denoted by a number that sequentially identifies each amino acid (or nucleotide base) in the reference sequence based on its position relative to an N-terminus (or 5′-end). Due to deletions, insertions, truncations, fusions, and the like that must be taken into account when determining an optimal alignment, in general the amino acid residue number in a test sequence determined by simply counting from the N-terminus will not necessarily be the same as the number of its corresponding position in the reference sequence. For example, in a case where a variant has a deletion relative to an aligned reference sequence, there will be no amino acid in the variant that corresponds to a position in the reference sequence at the site of deletion. Where there is an insertion in an aligned reference sequence, that insertion will not correspond to a numbered amino acid position in the reference sequence. In the case of truncations or fusions there can be stretches of amino acids in either the reference or aligned sequence that do not correspond to any amino acid in the corresponding sequence.
The terms “numbered with reference to” or “corresponding to,” when used in the context of the numbering of a given amino acid or polynucleotide sequence, refers to the numbering of the residues of a specified reference sequence when the given amino acid or polynucleotide sequence is compared to a reference sequence. In embodiments the reference sequence is a Candida intermedia GXS1 protein having SEQ ID NO: 1. In embodiments, the comparison to the reference sequence is a sequence alignment between the given amino acid or polynucleotide sequence and the reference sequence.
“GXS1 protein” or “Candida intermedia GXS1 protein” is used according to its common, ordinary meaning and refers to proteins of the same or similar names and functional fragments and homologs thereof. The term includes recombinant or naturally occurring forms of GXS1 protein (e.g. Genbank ID: CAI44932.1; GI: 85057135; SEQ ID NO: 1), or variants thereof that maintain GXS1 protein activity (e.g. within at least 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or 100% as compared to SEQ ID NO: 1). The term includes recombinant or naturally occurring forms of GXS1 protein or variants thereof that have sequence identity to SEQ ID NO: 1 (e.g. about 65%, 70%, 75%, 80%, 85%, 90%, 95%, 99% or 100% identity to SEQ ID NO: 1). GXS1 protein may refer to variants having mutated amino acid residues that modulate (e.g. increase or decrease when compared to GXS1 protein) GXS1 protein activity, expression, cellular targeting, or protein translocation. GXS1 protein may be modified as described herein (e.g. modified with a transporter motif sequence and/or glucose mitigation mutation).

Residues corresponding to positions 36-41 are underlined and bolded for reference. Residues corresponding to positions 155, 225, 326, 354, 361, 407 and 446 are underlined for reference.
The term “recombinant” when used with reference to, for example, a cell, nucleic acid, or protein, indicates that the cell, nucleic acid, or protein, has been modified by the introduction of a heterologous nucleic acid or protein or the alteration of a native nucleic acid or protein, or that the cell is derived from a cell so modified. Thus, for example, recombinant cells express genes that are not found within the native (non-recombinant) form of the cell or express genes otherwise modified from those found in the native form of a cell (e.g. genes encoding a mutation in a native or non-native transporter protein, such as a transporter motif sequence as described herein). For example, a recombinant protein may be a protein that is expressed by a cell or organism that has been modified by the introduction of a heterologous nucleic acid (e.g. encoding the recombinant protein).
The word “expression” or “expressed” as used herein in reference to a DNA nucleic acid sequence (e.g. a gene) means the transcriptional and/or translational product of that sequence. The level of expression of a DNA molecule in a cell may be determined on the basis of either the amount of corresponding mRNA that is present within the cell or the amount of protein encoded by that DNA produced by the cell (Sambrook et al., 1989 Molecular Cloning: A Laboratory Manual, 18.1-18.88).
The term “gene” means the segment of DNA involved in producing a protein; it includes regions preceding and following the coding region (leader and trailer) as well as intervening sequences (introns) between individual coding segments (exons). The leader, the trailer as well as the introns include regulatory elements that are necessary during the transcription and the translation of a gene. Further, a “protein gene product” is a protein expressed from a particular gene.
The term “isolated” refers to a nucleic acid, polynucleotide, polypeptide, protein, or other component that is partially or completely separated from components with which it is normally associated (other proteins, nucleic acids, cells, etc.). In embodiments, an isolated polypeptide or protein is a recombinant polypeptide or protein.
A “yeast cell” as used herein, refers to a eukaryotic unicellular microorganism carrying out metabolic or other function sufficient to preserve or replicate its genomic DNA. Yeast cells may carry out fermentation of sugars described herein. In embodiments, fermentation may convert the sugar to a biofuel or biochemical as set forth herein. Yeast cells referenced herein include, for example, the following species: Candida intermedia, Cryptococcos neoformans, Debaryomyces hansenii, Saccharomyces cerevisiae, Scheffersomyces stipitis, or Yarrowia lipolytica. A “recombinant yeast cell” is a yeast cell which expresses a recombinant transporter protein.
The term “biofuel” as used herein refers to a convenient energy containing substance produced from living organisms (e.g. biomass conversion to a fuel). Thus, biofuels may be produced through, for example, fermentation of carbohydrates (e.g. sugars) found in biomass (e.g. lignocellulosic biomass). Biofuels may be solid, liquid, or gas forms. Biofuels include, for example, ethanol, biodiesel, vegetable oil, ether (oxygenated fuels), or gas (e.g. methane).
The term “biochemical” as used herein refers to production of chemicals by living organisms. Biochemicals herein include production of alcohols (e.g. methanol, butanol, ethanol, isobutanol, 2,3-butanediol, propanol); sugars (e.g. erythritol, mannitol, riboflavin); carotenoids (e.g. β-carotene, lycopene, astaxanthin); fatty acids (e.g. ricinoleic acid, linolenic acid, tetracetyl phytosphingosine); amino acids (e.g. valine, lysine, threonine); aromatics (e.g. indigo, vanillin, sytrene, p-hydroxystyrene); flavonoids (e.g. naringenin, genistein, kaempferol, quercetin, chrysin, apigenin, luteolin); stillbenoids (e.g. resveratrol); terpenoids (e.g. β-amyrin, taxadiene, miltiradiene, paclitaxel, artemisinin, bisabolane); polyketides (e.g. aureothin, spectinabilin, lovastatin, geodin); acetone; or organic acids (e.g. citric acid, succinic acid, malic acid, lactic acid, polylactic acid, adipic acid, glucaric acid). See e.g. Curran K. A., Alper H. S., Metabolic Engineering 14:289-297 (2012).
A “transporter motif sequence” as used herein refers to an amino acid sequence that, when present in a protein (e.g. a sugar transporter protein such as a MFS transporter protein), increases the ability of the protein to transport a sugar or sugar-containing compound into a yeast cell. In embodiments, the transporter motif sequence imparts a hexose sugar transport preference or pentose sugar transport preference to the protein. Correspondingly, a transporter motif may refer to the specific sugar it transports into a yeast cell. For example, the transporter motif sequence may impart preference to hexose sugars to a transporter protein, thereby allowing the recombinant transporter protein to preferentially transport hexoses into a yeast cell. Such transporter motif sequences may be referred to herein as a “hexose transporter motif sequence.” In embodiments the transporter motif sequence imparts preference to a single hexose. The hexose may be galactose or mannose. Such transporter motif sequences may be referred to herein as a “galactose transporter motif sequence” and a “mannose transporter motif sequence” respectively. In embodiments, the transporter motif sequence imparts preference to more than one hexose sugar.
The transporter motif sequence may impart preference to pentose sugars to a transporter protein, thereby allowing the recombinant transporter protein to preferentially transport pentose into a yeast cell. In embodiments the transporter motif sequence imparts preference to a single pentose (e.g. xylose). The pentose may be xylose or arabinose. Such transporter motif sequences may be referred to herein as a “xylose transporter motif sequence” and an “arabinose transporter motif sequence” respectively. In embodiments the transporter motif sequence imparts preference to more than one pentose sugar (e.g. xylose and arabinose). Such transporter motif sequences may be referred to as a “xylose/arabinose transporter motif sequence.”
In embodiments, the transporter motif sequence imparts preference to a hexose and a pentose. That is, in embodiments, the recombinant transporter protein having such a transporter motif sequence preferentially transports one hexose and/or one pentose. Such transporter motif sequences may be referred to by the sugars which are transported (e.g. galactose and arabinose). Accordingly, in embodiments, the transporter motif sequence imparts preference to galactose and arabinose. Such a transporter motif is herein referred to as a “galactose-arabinose transporter motif sequence” (i.e. a recombinant transporter protein that transports both galactose and arabinose, or transports galactose or arabinose).
The transporter motif sequence as described herein corresponds to residues corresponding to positions 36-41 of the Candida intermedia GXS1 protein (“GXS1 motif sequence”). One skilled in the art will immediately recognize the identity and location of residues corresponding to positions 36-41 of the Candida intermedia GXS1 protein in other transporter proteins with different numbering systems. For example, by performing a simple sequence alignment with Candida intermedia GXS1 protein the identity and location of residues corresponding to positions 36-41 of the Candida intermedia GXS1 protein are identified in other yeast transport proteins as illustrated in Table 1. Insertion (e.g. substitution) of a transporter motif sequence into a yeast transport protein may thereby be performed resulting in a functional yeast transporter protein with an altered sugar transport preference (e.g. changing a preference for hexoses to a preference for pentoses). For example, amino acid residue positions 75-81 of S. cerevisiae HXT7 protein correspond to amino acid residue positions 36-41 of the Candida intermedia GXS1 protein (see Table 1).
C. intermedia GXS1 protein.
A “glucose mitigation mutation” as used herein refers to an amino acid mutation that, when present in a recombinant transporter protein, reduces, minimizes, diminishes, or in certain embodiments, eliminates the inhibitory effect of glucose on the recombinant transporter when transporting a sugar other than glucose (e.g. xylose) into a yeast cell. A glucose mitigation mutation may, in embodiments, increase the ability of a recombinant transporter protein to transport a preferred sugar or sugar-containing compound into a yeast cell. Thus, in embodiments, a glucose mitigation mutation may increase the ability of a recombinant transporter protein to transport xylose into a yeast cell. A glucose mitigation mutation may include a single amino acid residue mutation (e.g. a “point mutation”) in a recombinant transporter protein. A glucose mitigation mutation may include two or more mutations (e.g. a “substitution set”) in a recombinant transporter protein. The glucose mitigation mutation may be in a transmembrane domain, an extracellular loop, or cytoplasmic loop of a recombinant transporter protein. In embodiments, the glucose mitigation mutation may be localized (i.e. glucose mitigation mutations located within a specified domain or region of a recombinant transporter protein) or distributed (i.e. glucose mitigation mutations located throughout the sequence of the recombinant transporter protein).
A “recombinant transporter protein” as used herein refers to a recombinantly expressed transmembrane protein which transports a sugar or sugar-containing compound (e.g. hexoses and pentoses) into a yeast cell. In embodiments, the recombinant transporter protein is a yeast recombinant transporter protein. In embodiments, the recombinant transporter protein is a transporter protein belonging to the major faciliator superfamily (“MFS”) transporter proteins. In embodiments, a recombinant transporter protein may transport a hexose (e.g. galactose) into a yeast cell. In embodiments, a recombinant transporter protein may transport a pentose (e.g. xylose or arabinose) into a yeast cell. A recombinant transporter protein may be engineered, using the transporter motif sequences described herein, to alter its sugar preference (e.g. a transporter protein having a preference to transport a hexose compound may be converted to a transporter protein having a preference to transport a pentose compound). A recombinant transporter protein may be characterized by the sugar it transports. Thus, a recombinant transporter protein transporting xylose is herein referred to a “recombinant xylose transporter protein.” Likewise, recombinant transporter proteins transporting arabinose or galactose are herein referred to as a “recombinant arabinose transporter protein” and a “recombinant galactose transporter protein” respectively.
A recombinant transporter protein may be characterized as a transporter protein derived from a particular organism. Where a recombinant transporter protein is derived from a particular organism, the endogenous sequence of the recombinant transporter protein may be maintained and residues corresponding to positions 36-41 of the Candida intermedia GXS1 protein may be replaced with a transporter motif sequence. As an example, a C. intermedia gxs1 transporter protein is a gxs1 transporter protein, a homolog thereof, or a functional fragment thereof, found in C. intermedia. Amino acids 75-81 of S. cerevisiae hxt7 transporter protein may be replace with a transporter motif sequence thereby forming a recombinant transporter protein with desired sugar transport characteristics as described herein. In embodiments, the recombinant transporter protein is a protein, functional fragment, or homolog thereof, identified by the following NCBI gene ID or NCBI accession numbers: 836043, 831564, AJ937350.1, AJ875406.1, 2901237, 2913528, 8998057, 8999011, 50419288, 948529, 4839826, 4852047, 4851844, 4840896, 4840252, 4841106, 4851701, 2907283, 2906708, 2908504, 2909312, 2909701, 4935064, 851943, 856640, 851946, 856494, 8998297, 2902950, 2902912, 853207, 852149, 855023, 853216, 853236, 850536, 855398, 4836720, 4836632, 4840859, 2913215, 2902914, 2910370, and 4838168 (SEQ ID NOs:7-50, respectively in order of appearance). Such recombinant transporter proteins may further be characterized by the sugar preference conferred (e.g. a Candida intermedia GXS1 recombinant xylose transporter protein).
A “pentose compound” or “pentose” is a monosaccharide-containing compound having 5 carbon atoms. Pentose compounds include aldopentoses (e.g. pentose compounds having an aldehyde moiety at carbon 1) and ketopentoses (e.g. pentose compounds having a ketone moiety at carbon 2 or carbon 3). Pentose compounds include, for example, D/L-arabinose, D/L-lyxose, D/L-ribose, D/L-xylose, D/L-ribulose, and D/L-xylulose. The term “monosaccharide-containing” refers to a compound that includes at least one monosaccharide.
A “hexose compound” “or “hexose” is a monosaccharide-containing compound having 6 carbon atoms. Hexose compounds include aldohexoses (e.g. hexose compounds having an aldehyde moiety at carbon 1) and ketohexoses (e.g. hexose compounds having a ketone moiety at carbon 2). Hexose compounds include, for example, D/L-allose, D/L-altrose, D/L-glucose, D/L-mannose, D/L-glucose, D/L-idose, D/L-galactose, and D/L-talose.
A “xylose compound” is xylose or a xylose-containing compound including at least one xylose moiety. Thus as used herein, the term xylose compound represents a single xylose, a chain including one or more xylose moieties, or a xylose moiety covalently or non-covalently bound to another chemical moiety (e.g. another sugar forming a xylose containing polysaccharide or xylose bound to lignin). An “arabinose compound” is arabinose or an arabinose-containing compound including at least one arabinose moiety. Thus as used herein, the term arabinose compound represents a single arabinose, a chain including one or more arabinose moieties, or an arabinose moiety covalently or non-covalently bound to another chemical moiety (e.g. another sugar forming an arabinose containing polysaccharide or arabinose bound to lignin). A “galactose compound” is galactose or a galactose-containing compound including at least one galactose moiety. Thus as used herein, the term galactose compound represents a single galactose, a chain including one or more galactose moieties, or a galactose moiety covalently or non-covalently bound to another chemical moiety (e.g. another sugar forming a galactose containing polysaccharide or bound to lignin).
A “sugar” as set forth herein, refers to monosaccharide and polysaccharide compounds metabolized by a yeast cell. In embodiments, a sugar may be a hexose sugar as described herein or a pentose sugar as described herein.
Polysaccharides herein include hexose-only polysaccharides, pentose-only polysaccharides, and hexose-pentose mixture polysaccharides. In embodiments, the xylose compound, the arabinose compound, or the galactose compound may be derived from or form part of a lignocellulosic biomass (e.g. plant dry matter that may used in as a source for pentose compounds or hexose compounds and for production of biofuels or biochemicals), hemicellulose, marine biomass (e.g. seaweeds or algae that may used in as a source for pentose compounds or hexose compounds and for production of biofuels or biochemicals) or other natural or synthetic sources for xylose, arabinose, or galactose, including but not limited to xylan or pectin. “Derived from” refers to extraction, removal, purification, or otherwise freeing a xylose compound, arabinose compound, or galactose compound from a source (e.g. lignocellulosic biomass) by either chemical processes (e.g. acid hydrolysis, ammonium explosion, or ionic liquids extraction) or through natural biological processes by organisms capable of using such sources for energy.
A “xylose growth media” refers to a yeast cell media containing a xylose compound in amounts sufficient to serve as a nutrient for growing or culturing recombinant yeast cells. The term refers to a media substantially free of glucose, and, in embodiments, is “glucose free” (i.e. the media contains no glucose). In embodiments, a xylose growth media includes trace amounts of glucose which are undetectable using known methods and which are insufficient to support significant growth of yeast cells. In embodiments, a xylose growth media includes trace amounts of glucose which are insufficient to cause inhibition of activity of a recombinant transporter protein (e.g. a recombinant xylose transporter protein) as described herein.
A “xylose-glucose growth media” refers to a yeast cell media containing a xylose compound in an amount sufficient to serve as a nutrient for growing or culturing recombinant yeast cells and a glucose compound. The term refers to a media that includes glucose in an amount sufficient to serve as a nutrient for growth or culturing recombinant yeast cells or in an amount sufficient to cause inhibition of activity of a recombinant transporter protein as described herein. The glucose may be present in the xylose-glucose growth media at a pre-determined concentration as described herein.
Xylose growth media and xylose-glucose growth media may be supplemented with other hexoses or pentoses described herein (e.g. mannose, galactose, or arabinose). Growth of a recombinant yeast cell in a xylose growth media may be compared to growth of a recombinant yeast cell in a xylose-glucose growth media. Thus, in embodiments, a recombinant xylose transporter protein may be selected for its xylose selectivity and/or its rate of transfer of a xylose compound into a yeast cell by comparing its growth in xylose growth media to its growth in xylose-glucose growth media. In embodiments, recombinant yeast cells having impaired growth in xylose-glucose growth media may indicate that the recombinant xylose transporter protein in the recombinant yeast is inhibited, at least in part, by glucose.
An “arabinose growth media” refers to a yeast cell media containing an arabinose compound in amounts sufficient to serve as a nutrient for growing or culturing recombinant yeast cells. The term refers to a media substantially free of glucose, and, in embodiments, is “glucose free” (i.e. the media contains no glucose). In embodiments, an arabinose growth media includes trace amounts of glucose which are undetectable using known methods and which are insufficient to support significant growth of yeast cells. In embodiments, an arabinose growth media includes trace amounts of glucose which are insufficient to cause inhibition of activity of a recombinant transporter protein (e.g. a recombinant arabinose transporter protein) as described herein.
An “arabinose-glucose growth media” refers to a yeast cell media containing an arabinose compound in an amount sufficient to serve as a nutrient for growing or culturing recombinant yeast cells and a glucose compound. The term refers to a media that includes glucose in an amount sufficient to serve as a nutrient for growth or culturing recombinant yeast cells or in an amount sufficient to cause inhibition of activity of a recombinant transporter protein as described herein. The glucose may be present in the arabinose-glucose growth media at a pre-determined concentration as described herein.
Arabinose growth media and arabinose-glucose growth media may be supplemented with other hexoses or pentoses described herein (e.g. mannose, galactose, or xylose). Growth of a recombinant yeast cell in an arabinose growth media may be compared to growth of a recombinant yeast cell in an arabinose-glucose growth media. Thus, in embodiments, a recombinant arabinose transporter may be selected for its arabinose selectivity and/or its rate of transfer of an arabinose compound into a yeast cell by comparing its growth in arabinose growth media to its growth in arabinose-glucose growth media. In embodiments, recombinant yeast cells having impaired growth in arabinose-glucose growth media may indicate that the recombinant arabinose transporter protein in the recombinant yeast is inhibited, at least in part, by glucose.
A “galactose growth media” refers to a yeast cell media containing a galactose compound in amounts sufficient to serve as a nutrient for growing or culturing recombinant yeast cells. The term refers to a media substantially free of glucose, and, in embodiments, is “glucose free” (i.e. the media contains no glucose). In embodiments, a galactose growth media includes trace amounts of glucose which are undetectable using known methods and which are insufficient to support significant growth of yeast cells. In embodiments, a galactose growth media includes trace amounts of glucose which are insufficient to cause inhibition of activity of a recombinant transporter protein (e.g. a recombinant galactose transporter protein) as described herein.

The glucose may be present in the galactose-glucose growth media at a pre-determined concentration as described herein.
Galactose growth media and galactose-glucose growth media may be supplemented with other hexoses or pentoses described herein (e.g. mannose, arabinose, or xylose). Growth of a recombinant yeast cell in a galactose growth media may be compared to growth of a recombinant yeast cell in a galactose-glucose growth media. Thus, in embodiments, a recombinant galactose transporter may be selected for its galactose selectivity and/or its rate of transfer of a galactose compound into a yeast cell by comparing its growth in galactose growth media to its growth in galactose-glucose growth media. In embodiments, recombinant yeast cells having impaired growth in galactose-glucose growth media may indicate that the recombinant galactose transporter protein in the recombinant yeast is inhibited, at least in part, by glucose.
As defined herein, the term “inhibition”, “inhibit”, “inhibiting” and the like refers to negatively affecting (e.g. decreasing) the activity or function of a recombinant transporter protein (e.g. recombinant xylose transporter protein) relative to the activity or function of the protein in the absence of the inhibitor (e.g. glucose). In embodiments, inhibition refers to a reduction in the growth rate of a recombinant yeast cell.
“Contacting” is used in accordance with its plain ordinary meaning and refers to the process of allowing at least two distinct species (e.g. chemical compounds including sugars, biomolecules or cells) to become sufficiently proximal to react, interact or physically touch. The term “contacting” includes allowing two species to react, interact, or physically touch, where the two species may be a sugar as described herein and a recombinant transporter protein as described herein. In embodiments contacting includes allowing a sugar described herein to interact with a recombinant transporter protein that is involved in transporting hexose or pentose compounds into a yeast cell.

2. Recombinant Yeast Cell Including a Recombinant Arabinose Transporter Protein
In another aspect is a recombinant yeast cell that includes a recombinant arabinose transporter protein as described herein, including embodiments thereof. In embodiments, the growth rate of the recombinant yeast cell including a recombinant arabinose transporter protein as described herein can be measured. The growth rate may be determined in arabinose growth media (i.e. in the absence of glucose). The growth rate may be determined in arabinose-glucose growth media. In embodiments, the growth rates (i.e. growth rate in the absence and presence of glucose) are compared to determine the differential growth rate of the recombinant yeast cells. If the growth rate of recombinant yeast cells grown in arabinose-glucose growth media is less than the growth rate of recombinant yeast cells grown in arabinose growth media, the differential growth rate may indicate glucose inhibits the activity of the recombinant arabinose transporter protein. As described herein, inclusion of a glucose mitigating mutation decreases, minimizes, or may eliminate glucose inhibition of the recombinant arabinose transporter protein.

3. Recombinant Yeast Cell Including a Recombinant Galactose Transporter Protein
In another aspect is a recombinant yeast cell that includes a recombinant galactose transporter protein as described herein, including embodiments thereof. In embodiments, the growth rate of the recombinant yeast cell including a recombinant transporter protein as described herein can be measured.

In previous research, was developed a xylose specific transporter hereafter termed “CiGXS1-FIM” (“FIM”), based on a hexose transporter from C. intermedia, GXS1. The FIM mutation imparted specificity in transporting xylose over glucose. (11) The presence of glucose, however, inhibited the performance of FIM in transporting xylose. Herein directed evolution was conducted to reduce the observed glucose inhibition.
A library of randomly mutated FIM was generated by error-prone PCR with a library size of over 1×105 mutants (as measured by independent E. coli colonies post-transformation). The mutant FIM was then transformed into S. cerevisiae ETKXG strain, a triple hexokinase knockout strain which is not able to grow on glucose, and screened on the xylose dependent growth based advantage on the dropout plates with 20 g/L of xylose and 2.5 g/L of glucose. The 140 selected mutants from the plates were then tested for the growth on the medium with 20 g/L of xylose and 2.5 g/L glucose using Bioscreen C and the top 6 mutants were selected for further confirmation. The growth rates of the selected mutants on xylose in the presence of various concentration of glucose were then confirmed using Bioscreen C (
The mutant 105, which has 6 mutations: K155E, N225D, S354T, A361T, L407M, N446S (
The mutant 78, which has a single mutation, N326S, showed reduced glucose inhibition without decrease in xylose transport capability. In contrast to mutant 105, mutant 78 showed no reduction in the xylose transport performance. This suggests the mutant 78 represents a promising candidate for further round of directed evolution to develop xylose transporters with reduced glucose inhibition.
