Description

DESCRIPTION

Secondary-metabolite biosynthesis genes from actinomycetes, method of isolating them and their use.

The invention concerns secondary-metabolite biosynthesis genes from actinomycetes, a method of isolating secondary-metabolite and, in particular, 6-deoxy-sugar bio-synthesis genes, from actinomycetes using the gene probes strD, strE, strL and strM gene probes from Streptomyces griseus DSM40236, and structurally related genes, as gene probes for detecting the genes snot (coding for amphotheronolide B-dTDP-D-mycosaminyl transferase), snoD (coding for dTDP-D-glucose synthase) and snoM (coding for dTDP-4-keto-6-deoxy-D-glucose isomerase), or one or more secondary-metabolite biosynthesis genes from actinomycetes. The invention also concerns the use of secondary-metabolite biosynthesis genes thus isolated.

One of the fields of activity in recombinant DNA technology is the isolation of particular genes directly out of the genome. In order to detect the gene to be isolated, gene probes can, for example, be employed which bind specifically to the desired DNA sequence. In this way, this latter sequence can be "fished out" (detracted by screening) from a large number of other sequences.

Secondary-metabolite biosynthesis genes (genes for antibiotics, anthelmintics, antifungal substances, enzyme inhibitors, dyes, etc.) which have hitherto been investigated are present adjacent to each other within a unit on the bacterial chromosome or on very large plasmids. This applies particularly to streptomycetes and other actinomycetes �C. L. Hershberger et al. (1989), Genetics and Molecular Biology of Industrial Microorganisms, Am. Soc. for Microbiol., Washington, D.C. 20005, pp. 35-39, p. 58, pp. 61-67, pp. 147-155!.

Thus, in actinomycetes, genes for the biosynthesis of 6-deoxy sugars, for example, are located on the genome in close proximity to other secondary-metabolite biosynthesis genes �J. F. Martin et al. (1989), Ann. Rev. Microbiol 43: 173-206!.

In addition to this, it is known that a multiplicity of secondary metabolites from actinomycetes contain 6-deoxy sugar residues. Examples are, inter alia, aminoglycosides (e.g. spectinomycin, kasugamycin and streptomycin), polyenes (e.g. amphotericin A and B, and nystatin), macrolides (e.g. tylosin, erythromycin and avermectin), nucleosides (e.g. antibiotic A201A) and anthracyclines (e.g. daunorubicin and cytorhodin A) and glycopeptides (e.g. vancomycin) and isochromanequinones (e.g. granaticin).

The pathway for the biosynthesis of a 6-deoxy sugar residue of streptomycin, the L-dihydrostreptose residue, is depicted in FIG. 1.

Until recently, there were still no sequence data available for actinomycetes genes or enzymes which are involved in the biosynthesis of 6-deoxy sugars. As a result of cloning and analyzing the genes for the biosynthesis of streptomycin, it was possible to isolate and identify the genes for the 6-deoxy sugar component, L-dihydro-streptose:

strD (dTDP-D-glucose synthase), strE (dTDP-D-glucose 4,6-dehydratase), strM (dTDP-4-keto-L-rhamnose 3,5-epimerase) and strL (dTDP-L-dihydrostreptose synthase) from Streptomyces griseus DSM40236.

The use of heterologous gene probes, i.e. gene probes which are employed for screening in another species or for isolating genes within another biosynthesis pathway, for the isolation of secondary-metabolite biosynthesis genes has thus far been limited to only a few genes (e.g. polyketide synthetase genes) �Nature (1987) 325: 818-821!. Using these polyketide synthetase gene probes, it is only possible to detect compounds which are formed via the polyketide synthetase biosynthesis pathway �C. L. Hershberger et al. (1989), Genetics and Molecular Biology of Industrial Microorganisms, Am. Soc. for Microbiol., Washington, D. C. 20005, pp. 76-78; S. L. Otten et al., J. Bacteriol. 172, No. 6 (1990), pp. 3427-3434!, and not functionally different genes, such as aminoglycoside biosynthesis genes, for example.

It has now been found, surprisingly, that one or more gene probes from the strD, strE, strL or strM group of genes from Streptomyces griseus DSM40236, and structurally related genes, are suitable for use as gene probes for detecting the genes snot (encoding amphotheronolide B-dTDP-D-mycosaminyl transferase), shod (encoding dTDP-D-glucose synthase) and snoM (encoding dTDP-4-keto-6-deoxy-D-glucose isomerase), or one or more secondary-metabolite biosynthesis genes from actinomycetes. The screening for the secondary-metabolite biosynthesis genes does not depend on the chemical structure of the secondary metabolites. The only prerequisite is that they possess 6-deoxy sugar residues.

The invention therefore discloses:

The complete DNA sequence of snot and shod as well as part of the DNA sequence of snoM.

The complete amino acid sequence of snot and shod as well as part of the amino acid sequence of snoM.

A method for isolating secondary-metabolite biosynthesis genes from actinomycetes, wherein one or more genes from the strD, strE, strL or strM group of genes from Streptomyces griseus DSM40236, and structurally related genes, are used as gene probes for detecting the genes snot (encoding amphotheronolide B-dTDP-D-mycosaminyl transferase), shod (encoding dTDP-D-glucose synthase) and snoM (encoding dTDP-4-keto-6-deoxy-D-glucose isomerase), or one or more secondary-metabolite biosynthesis genes from actinomycetes.

The use of the isolated secondary-metabolite biosynthesis genes for forming hybrid natural substances.

The use of the isolated secondary-metabolite biosynthesis genes for increasing the yield of secondary metabolites in actinomycetes.

The use of the isolated secondary-metabolite biosynthesis genes for isolating biosynthesis enzymes.

The use of the isolated secondary-metabolite biosynthesis genes for biotransformation in actinomycetes.

The use of the isolated secondary-metabolite biosynthesis genes for screening secondary-metabolite producers.

The invention is described in detail below. In addition, the invention is determined by the content of the claims.

All methods involving recombinant DNA technology were, unless otherwise indicated, taken from J. Sambrook et al. (Molecular Cloning; A laboratory manual �2nd edition! 1989; Cold Spring Harbor Laboratory Press, N.Y., USA).

The gene probes strD, strE, strL and strM, which are required for the screening, are deposited, in the E. coli strains FH-L 8138 (strD), FH-L 8154 (strE), FH-L 8158 (strL) and FH-L 8159 (strM), with the Deutsche Sammlung yon Mikroorganismen und Zellkulturen GmbH (German collection of microorganisms and cell cultures) (DSM), 3300 Braunschweig, Mascheroder Weg 1b, Germany, on 30.08.1991 under the following numbers DSM6681 (FH-L 8138), DSM6682 (FH-L 8154), DSM6683 (FH-L 8158) and DSM6684 (FH-L 8159). The plasmids pJDM1018 (strD), pKMW1 (strE), pKMW2 (strL) and pKPD12 (strM) �see FIG. 2! are isolated from the abovementioned E. coli strains using the boiling method and by alkaline lysis (J. Sambrook et al. 1989).

The plasmids pJDM1018 (strD), from E. coli DSM6681, and pKMW1 (strE), from E. coli DSM6682, are cut with the restriction enzymes EcoRI and HindIII. A 0.7 kb EcoRI/HindIII fragment of the plasmid pJDM1018 and a 1.2 kb EcoRI/HindIII fragment of the plasmid pKMW1 are isolated and provided with .sup.32 P-labeled deoxynucleotides using so-called "nick translation". These radioactively labeled fragments are designated below as gene probes strD and strE, respectively.

A 0.8 kb EcoRI-HindIII fragment is isolated from the plasmid pKMW2 (strL) from E. coli DSM6683, as is a 0.5 kb SmaI fragment from the plasmid pKPD12 (strM) from E. coli DSM6684, and these fragments are then radioactively labeled and employed as gene probe strL and strM, respectively.

In principle, any other extended, truncated or modified fragment or synthetic oligodeoxynucleotide can be used as a gene probe in place of the abovementioned gene probes as long as it hybridizes with the gene for the biosynthesis of deoxysugar residues.

The procedure for isolating one or more secondary-metabolite biosynthesis genes is as follows:

The total DNA of any one of the actinomycetes strains listed in Table 1 can be isolated, cleaved using the restriction endonuclease BamHI, and other restriction enzymes, and fractionated by gel chromatography. The total DNA of Streptomyces nodosus DSM40109 is preferably used.

Hybridization with 6-deoxy sugar gene probes, preferably with the strD gene probe, then takes place. The DNA fragments, preferably those of 1.5-3 kb in size, which hybridize with the 6-deoxy sugar gene probes, preferably with the strD gene probe from S. nodosus DSM40109, are isolated from the gel and ligated into a suitable vector and then cloned in a microorganism which is compatible for the vector.

The vectors pUC18 (Boehringer Mannheim, Germany) and pEB15 from S. coelicolor Muller DSM4914, and the host strains E. coli K12 and S. lividans 66, are preferably employed. E. coli DH5alpha (Gibco BRL, Eggenstein, Germany) and S. sp DSM40434 are very preferably used.

The clones containing plasmid DNA are isolated and hybridized with the respective gene probe, preferably with the strD probe from S. griseus DSM40236. In this context, pools of ten can in each case be used, which pools can then be split into the individual clones if hybridization occurs, with the plasmids being isolated and subjected once again to hybridization. A plasmid which hybridizes with a gene probe is cleaved by restriction enzymes. Hybridizing restriction fragments, preferably those which hybridize with the strD gene probe from S. nodosus DSM40109, are isolated and subcloned into a vector, preferably pUC18, and into a host strain, preferably E. coli DH5alpha, and then examined by DNA sequence analysis.

If appropriate, that region of the cloned fragment which is to be sequenced can be delimited more closely by repeating the subcloning prior to the DNA sequence analysis, and subclones which are suitable for the sequencing can be identified by hybridization, preferably using the strD gene probe.

Preferably, the 2.6 kb BamHI fragment which is isolated from the total DNA of the amphotericin B-producer S. nodosus DSM40109, and which hybridizes with the strD probe, is cloned into the vector pEB15 in S. sp. DSM40434. The resultant plasmid pPS72.2 (see FIG. 3A) is cleaved with restriction enzymes, e.g. with SmaI-SstI, and the DNA fragments which are obtained are subcloned in pUC18 in E. coli DH5alpha, and sequenced.

For the subcloning, the abovementioned DNA fragments are isolated. Preferably, the 1.4 kb SmaI/SstI and the 1.45 kb SmaI fragments are isolated from the plasmid pPS72.2 and then subcloned into pUC18, resulting in the production of the plasmids pPS1 and PSab1 (FIG. 3A). Preferably, the 0.4 kb EcoRI fragment is isolated from plasmid pSab1 and cloned, in both possible orientations, into pUC18 in E. coli DH5alpha, resulting in the production of the plasmids pSab2.1 and pSab2.2 (see FIG. 3A); the 3.7 kb EcoRI fragment of plasmid pSab1 is isolated, religated and transformed into E. coli DH5alpha, resulting in the production of the plasmid pSab3 (see FIG. 3A).

The plasmids which contain a DNA fragment hybridizing with a gene probe are used for the DNA sequencing. Preferably, the 2.6 kb BamHI fragment of S. nodosus DSM40109, contained in plasmid pPS72.2, is sequenced completely and in both strand directions. Plasmid pPS72.2, and the plasmids pPS1, pSab1, pSab3, pSab2.1 and pSab2.2 derived from it, are preferably used for this purpose, once they have been isolated by alkaline lysis and purified by being subjected twice to cesium chloride gradient centrifugation.

The method of A. M. Maxam and W. Gilbert (1977) Proc. Natl. Acad. Sci. USA 74:560-564 or that of F. Sanger et al. (1977) Proc. Natl. Acad. Sci. USA (1977) 74:5463-5467, or a process derived from one of these methods, is employed for the DNA sequencing. The Promega fmol# sequencing system, which operates in accordance with the method of Sanger (Serva, Heidelberg, Germany), is preferably used.

Suitable primers are either obtained from commercial sources (pUC reverse-sequencing and sequencing primers, Boehringer Mannheim, Germany) or else synthesized (see Table 2) as described in EP-A-0,368,244 (Example 16).

Open reading frames, or parts thereof, are recognized from the codon usage which is characteristic for streptomycetes (F. Wright et al. 1992, Gene 113:55-65) and from the presence of a start codon (ATG or GTG) and/or a stop codon (TAG, TGA or TAA). Amino acid sequences deduced from the DNA sequence are compared with the amino acid sequences of known gene products. The analysis of open reading frames is preferably carried out using the FASTA or TFASTA programs of the Database Searching Program, Version 7, of the GCG Package, Genetics Computer Group Inc. Wis., USA). This then involves searching one or more of the SwissProt, NBRF-Protein (Pir), Genbank and/or EMBL databases for sequences which are similar to the open reading frame which has been identified. Conclusions are drawn with regard to the function of the relevant gene product from a comparison of its amino acid sequence with that of known proteins and comparison with the assumed pathway for the biosynthesis of dTDP-D-mycosamine (Juan-Francisco Martin, Biosynthesis of Polyene Macrolide Antibiotics; Ann. Rev. Microbiol. 1977, 31:13-38).

Alternatively, the DNA sequences can also be compared with known DNA sequences and corresponding reading frames.

The gene products which are designated snoM, snot and snoD, and which encode dTDP-4-keto-6-deoxy-D-glucose 3,4-isomerase, B-dTDP-mycosaminyl transferase and dTDP-D-glucose synthase, are preferably identified.

Besides this, the identified snoM, snot and shod genes can be employed for detecting novel secondary metabolites containing 6-deoxy sugars.

All actinomycetes genes relating to the biosynthesis of 6-deoxy sugars, but particularly the L-dihydrostreptose biosynthesis genes strL and strM, and very preferably the genes strD and strE from Streptomyces griseus DSM40236, are suitable for use as gene probes for detecting novel secondary-metabolite and 6-deoxysugar biosynthesis genes in actinomycetes.

Instead of the strD, strE, strL and strM gene probes from Streptomyces griseus DSM40236, genes which are functionally and structurally similar, such as those from the hydroxystreptomycin producer Streptomyces glaucescens DSM40716, the candicidin producers Streptomyces coelicolor DSM40624 and Streptoverticillium sp. DSM40237, the perimycin producer Streptomyces aminophilus DSM40186, the pimaricin producer Streptomyces sp. DSM40357, the lucensomycin producer Streptomyces lucensis DSM40317, the rimocidin producer Streptomyces rimosus DSM40260, the levorin A2 producer Streptomyces sp. DSM40202, the lienomycin producer Streptomyces lienomycini ATCC43687, the monazomycin producer Streptoverticillium mashuense NRRL B-3352, the picromycin producers Streptomyces felleus DSM40130 and Streptomyces olivaceus DSM40702, the narbomycin producer Streptomyces narbonensis DSM40016, or the methymycin producers Streptomyces venezuelae ATCC15068 and ATCC15439, for example, may also be employed as probes which are specific for secondary metabolites.

The genes from the amphotericin B producer Streptomyces nodosus DSM40109, the nystatin producer Streptomyces noursei DSM40635, the rhodomycin producer Streptomyces purpurascens DSM2658 and the streptomycin producer Streptomyces griseus DSM40236 are preferably used.

In addition to this, the gene probes which are specific for secondary metabolites can be used for:

Forming hybrid natural substances: For this purpose, the said gene probes are used for the transfer of isolated genes into a different actinomycetes strain in order to cause this strain to synthesize a novel secondary metabolite. In this context, the 6-deoxy sugar biosynthesis genes and transferase genes, and other secondary-metabolite biosynthesis genes as well, are particularly suitable for use in the formation of novel hybrid natural substances. Increasing the yield of secondary metabolites in actinomycetes: In some actinomycetes strains, the activity of the enzymes for the biosynthesis of 6-deoxy sugars is limited by different factors. By means of cloning the 6-deoxy-sugar biosynthesis genes from an actinomycetes strain and then reintroducing the cloned gene into this -strain at higher copy number, the yield of gene products, and thus the level of secondary-metabolite production, can be increased. This also applies to other cloned secondary-metabolite biosynthesis genes. Isolating biosynthesis enzymes: The chemical synthesis of 6-deoxy sugars is costly, since it requires sophisticated protective group technology. It is advantageous to use enzymes to synthesize the sugars in vitro without the need for protective groups. The preparation of the 6-deoxy-sugar biosynthesis enzymes for the enzymic synthesis is facilitated if the above-described 6-deoxy-sugar biosynthesis genes are present at increased copy number. Carrying out biotransformations in actinomycetes: The glycosylation of a secondary-metabolite precursor (natural aglycone) in an actinomycetes strain is brought about by the products of 6-deoxy-sugar biosynthesis genes and transferase genes. Other compounds (foreign aglycones) can be fed to a strain and be glycosylated. By means of self-cloning 6-deoxy-sugar biosynthesis genes and transferase genes, i.e. cloning the genes from a strain and reintroducing them into the same strain at a high copy number, the rate at which a foreign (fed) aglycone is glycosylated is then increased. Identifying other genes: As already mentioned in the introduction, gene probes can also be used to isolate genes which are structurally and functionally novel and for which no previous sequence homology is known. Screening secondary-metabolite producers: Producers of secondary metabolites which contain 6-deoxy sugars are identified with the aid of the abovementioned gene probes. This leads in turn to the isolation of novel secondary metabolites.

EXAMPLE

1. Cultivation of E. coli Strains, Preparation of Plasmid DNA and Isolation of DNA Fragments

The strains E. coli DSM6681 (contains the strD gene on plasmid pJDM1018) and E. coli DSM6682 (contains the strE gene on plasmid pKMW1) are in each case cultivated at 37.degree. C. for 16 hours in 1 liter of Luria Bertani (LB) medium (1% Bactotryptone, 0.5% Bactoyeast extract, 1% sodium chloride, pH 7.0) which is supplemented with 100 .mu.g/ml ampicillin after autoclaving. The plasmids pJDM1018 and pKMW1 are isolated from these strains by alkaline lysis and are subsequently subjected twice to cesium chloride density gradient centrifugation, as described in J. Sambrook et al. (1989).

5 U each of EcoRI and HindIII (from Boehringer Mannheim, Mannheim, Germany) are added in each case to 10 .mu.g of the isolated plasmid DNA in 10 mM Tris-HCl, pH 8.0, 5 mM MgCl.sub.2, 100 mM NaCl, 1 mM mercaptoethanol, and the mixtures are then incubated at 37.degree. C. for 2 hours.

The cleaved plasmid DNA is in each case loaded onto a horizontal 0.8% agarose gel and fractionated by electrophoresis (J. Sambrook et al. 1989).

Using a scalpel, a narrow pocket is cut out of the agarose gel immediately in front of the 0.7 kb and 1.2 kb, respectively, EcoRI/HindIII fragments of the two plasmids pJDM1018 and pKMW1, and then filled with TBE buffer (0.045M Tris-borate, 0.001M EDTA, pH 8.0). The DNA fragments are transferred electrophoretically into the pockets as described in T. Maniatis et al. (1989). The buffer is then removed from the pockets and extracted with phenol/chloroform and chloroform/isoamyl alcohol, and the DNA is subsequently precipitated with absolute ethanol and washed with 70% ethanol; the DNA sediment which has been obtained is then dried and dissolved in 50 .mu.l TE buffer (10 mM Tris-HCl, 0.1 mM EDTA, pH 8.0).

2. Preparation of the StrD and StrE Gene Probes

5 .mu.g of the DNA fragments which derived from plasmids pJDM1018 and pKMW1 (strD gene and strE gene, respectively), and which were prepared in accordance with point 1, are incubated at 15.degree. C. for 35 minutes in 50 mM Tris-HCl, pH 7.5, 10 mM MgSO.sub.4, 0.1 mM dithiothreitol, 50 .mu.g/ml bovine serum albumin (fraction V, from Sigma, Deisenhofen, Germany) together with 5 U E. coli DNA polymerase I (nick translation grade, Boehringer Mannheim, Germany) and 50 .mu.M dATP and 50 .mu.M dTTP, and 40 .mu.Ci each of �.alpha..sup.-32P !-dCTP and �.alpha..sup.32P !-dGTP (3000 Ci/mmol; from DuPont de Nemours, NEN Division, Dreieich, Germany). The reaction is stopped by adding 0.02 mM EDTA, pH 8.0, and heating at 65.degree. C. for 10 minutes. Unincorporated radionucleotides are separate8 off, as described in J. Sambrook (1989), by gel filtration in TE buffer (10 mM Tris-HCl, 0.1M EDTA, pH 8.0) on a 0.5.times.10 cm Sephadex G15 column.

The radioactively labeled 0.7 kb and 1.2 kb EcoRI/HindIII fragments, deriving from plasmids pJDM1018 and pKMW1, respectively, and having been purified by gel filtration, are designated the strD and strE gene probes, respectively; immediately prior to use, they are denatured at room temperature for 5 minutes with 0.3M sodium hydroxide solution, then neutralized with 0.3M HCl and 0.3 Tris-HCl pH 7.0, boiled for 5 minutes and immediately cooled in ice water.

3. Isolation, Cleavage and Fractionation by Gel Electrophoresis of Streptomycetes total DNA

The streptomycetes strains S. nodosus DSM40109 and NRRLB-2371, S. noursei DSM40635 and NRRLB-1714, S. aminophilus DSM40186, S. lucensis DSM40317, S. venezulae NRRLB-2447, S. narbonensis DSM40016, S. griseus DSM40236 and S. glaucescens DSM40716 are cultivated at 30.degree. C. for three days in 100 ml CASO broth (casein peptone-soya bean meal-peptone broth, from Merck, Darmstadt, Germany). The total DNA of these strains is isolated by the method described in D. A. Hopwood et al. (1985), Genetic manipulation of Streptomyces; A laboratory manual; The John Innes Foundation, Norwich, England.

The genomic DNA of S. purpurascens DSM2658 is isolated from protoplasts which are prepared in accordance with D. A. Hopwood et al. (1985) and frozen down at -20.degree. C.

The protoplasts of strain S. purpurascens DSM2658 are thawed rapidly at 37.degree. C. and then centrifuged in a bench centrifuge (Z 231M, from Hermle) at 3000 rpm for 7 minutes. The sedimented protoplasts are lysed at 60.degree. C. for 1 hour in 10 mM Tris-HCl, 5 mM EDTA, pH 7.8, 0.5% SDS and 0.2 mg/ml proteinase K. The mixture is adjusted to 5 mM EDTA, pH 8.0, 1% SDS and 1M NaCl and placed in ice water for 2 hours. Following centrifugation at 10,000 rpm for 30 min at 4.degree. C., the supernatant is transferred into a 1.5 ml Eppendorf tube, the lid of which has a hole pierced by a red-hot spatula. A dialysis membrane is stretched between the opening of the tube and its lid, and the lid is then closed and sealed with parafilm. The tube is then dialyzed twice at 4.degree. C. for 5 hours in 0.5 liter 10 mM Tris-HCl, pH 7.5.

10 .mu.g of total DNA isolated from each of the Streptomycetes strains investigated are incubated at 37.degree. C. for 2 hours in 10 mM Tris/HCl, pH 8.0, 5 mM MgCl.sub.2, 100 mM NaCl and 1 mM mercaptoethanol together with 10 U BamHI and 1 U DNase-free bovine pancreatic RNase (Boehringer Mannheim, Germany).

The cleaved Streptomycetes genomic DNA and the molecular weight standards (HindIII and EcoRI/Hind-III fragments of .lambda. DNA, Boehringer Mannheim) are fractionated on an 0.8% agarose gel and then photographed under UV illumination (254 nm).

4. Transfer of DNA Go Membranes (Southern Transfer)

DNA fragments are transferred from agarose gels to membranes essentially in accordance with the method described by E. M. Southern (1975) J. Mol. Biol. 98: 503-517. The agarose gel obtained in accordance with point 3 is tilted in 0.24M hydrochloric acid for 15 minutes and then treated for 20 minutes with 0.4M sodium hydroxide solution. The gel is laid on 2 layers of absorbent paper (Whatman 3MM-Chr, from Whatman International Ltd., Maidstone, England), and a Hybond.TM.-N+ membrane (from Amersham, Braunschweig, Germany) is stretched over it while ensuring that no air bubbles are trapped. As described in J. Sambrook et al. (1989), a plurality of layers of absorbent paper are then stacked on the membrane. A weight of approximately 1 kg is then placed on the filter paper stack. The DNA is transferred by 0.4M sodium hydroxide solution being sucked through. After transfer has taken place for 16 hours, the nylon filter is briefly rinsed with 0.9M sodium chloride and 0.09M trisodium citrate, and then baked at 80.degree. C. for 2 hours in a drying oven.

5. DNA Hybridization and Autoradiography

The nylon filter, which is treated as described under point 4, is tilted at 68.degree. C. for two hours in 50 ml of prehybridization solution (0.9M sodium chloride; 0.09M trisodium citrate, 0.5% SDS, 20 .mu.g/ml denatured herring sperm DNA, 0.1% bovine serum albumin (fraction V, sigma), 0.1% ficoll (type 400, from Sigma, 0.1% polyvinylpyrrolidone MW =approximately 40,000 d, from Sigma). The prehybridization solution is poured off and 50 ml of hybridization solution, which contains the denatured strD or strE gene probe in prehybridization solution without herring sperm DNA, is added. The hybridization is carried out at 68.degree. C. for 16 hours while shaking gently. The filters are then washed at 68.degree. C. for 15 minutes in 0.3M sodium chloride, 0.03M trisodium citrate and 0.5% SDS, and then at 68.degree. C. 3 times for 15 minutes in 0.075M sodium chloride, 0.0075M trisodium citrate and 0.5% SDS. The filters are dried at room temperature, laid on a Whatman 3MM-Chr filter paper and covered with vacuum-sealing foil. Autoradiography is carried out at -80.degree.

Isolation and cloning of BamHI fragments from the total DNA of Streptomyces nodosus DSM40109

The total DNA from S. nodosus DSM40109 is isolated, cleaved completely with BamHI and fractionated by agarose gel electrophoresis (see Example 3). BamHI fragments which are from 1.5 to 3 kb in length are isolated out of the gel (see Example 1).

The vector plasmid is isolated from the strain S. coelicolor Muller DSM4914 pEB15 by the method described in D.A. Hopwood et al. (1985) p. 85 ff., and then cleaved with BglII and treated with alkaline phosphatase (calf intestinal phosphatase, Boehringer Mannheim, Germany) in accordance with the methods described in EP-0-368-224 (Example 2). In each case, 1 .mu.g of the BglII-cleaved, dephosphorylated vector DNA is incubated at 16.degree. C. for 16 hours in a 20 .mu.l reaction mixture containing 5 .mu.g of isolated 1.5 kb to 3 kb BamHI fragments from the total DNA of S. nodosus DSM40109 and 1 U of T4 DNA ligase (Boehringer Mannheim) in ligase buffer (66 mM Tris-HCl, pH 7.5, 5 mM MgCl.sub.2, 1 mM dithiothreitol, 1 mM ATP). Protoplasts of S. sp. DSM40434 are prepared in accordance with D.A. Hopwood et al. pages 12 ff. The ligase mixture is transformed into S. lividans DSM40434 protoplasts as described in Hopwood et al. pages 110 ff. Thiostreptone-resistant transformants are cultivated at 30.degree. C. for 3 days in 2.5 ml of CASO broth (Merck, Darmstadt) to which 30 .mu.g/ml thiostreptone has been added. The plasmid DNA is isolated by the method described in Hopwood et al. pages 85 ff., cut with ClaI and fractionated by gel electrophoresis. At least 30% of the transformants investigated harbor a plasmid of the size of 6.8 kb to 8.3 kb.

7. Identification of Clones which Contain dTDP-D-glucose Synthase Genes

In each case, ten of the clones obtained in accordance with Example 6 are cultivated at 30.degree. C. for three days in 2.5 ml of CASO broth containing 30 .mu.g/ml thiostreptone. The plasmid DNA is then isolated from a total of 200 of these so-called pools of ten (Hopwood, pages 85 ff.). 5 .mu.l of each of the isolated plasmid DNA samples is heated at 96.degree. C. for 10 minutes and then cooled rapidly in ice water. 3 .mu.l of the denatured plasmid DNA from each pool are then transferred onto a membrane (Hybond.TM.-N+, Amersham Buchler, Braunschweig, Germany) in a regular pattern at intervals of 1.5 cm in each case. After having been dried at room temperature, the membrane is laid for 5 minutes on a filter paper (Whatman 3MM-Chr, Whatman International Ltd. Maidstone, England) which has been soaked in denaturation buffer I (1.5M NaCl, 0.5M NaOH). Subsequently, filter papers are employed for 1 min and 20 min which have been soaked in neutralization solution (1.5M NaCl, 0.5M Tris-HCl, pH 7.2, 1 mM EDTA) and denaturation buffer II (0.4M NaOH), respectively. The Hybond.TM.-N+ membrane is rinsed with 5-fold concentrated SSC solution (corresponds to 0.75M sodium chloride, 0.075M trisodium citrate, pH 7.5), and then hybridized with the strD probe (see Example 2) as described in Example 5.3 out of 200 pools of ten hybridize with this probe. A selected pool is split into the ten individual clones whose plasmid DNA is then isolated and hybridized with the strD probe (see Example 2) as described in Example 5. The hybridizing plasmid is designated pPS72.2 (see FIG. 3B). It contains a 2.6 kb BamHI fragment cloned into the vector pEB15.

8. Subcloning of Plasmid pPS72.2

Plasmid pPS72.2 is isolated by cesium chloride density gradient centrifugation from the S. lividans clone isolated in accordance with Examples 6 and 7 (Hopwood et al., pp. 87, 82 and 93). The plasmid is cleaved with SmaI and SstI, and the resultant 1.4 kb SmaI/SstI fragment is isolated out of the gel. The vector plasmid pUC18 is obtained from Boehringer Mannheim, Germany, and cut with SmaI and SstI, and the 2.7 kb fragment is isolated. 1 .mu.g of each of the isolated 1.4 kb and 2.7 kb fragments are together treated with T4 DNA ligase and then transformed into competent E. coli DH5alpha cells (MAX Efficiency DH5Alpha.TM. competent cells, Gibco BRL, Eggenstein, Germany) in accordance with the manufacturer's instructions and selected at 37.degree. C. for 16 hours on LB plates (see Example 1) containing 100 .mu.g/ml ampicillin. Ampicillin-resistant colonies are cultured at 37.degree. C. for 16 hours in 2.5 ml of LB medium containing 100 .mu.g/ml ampicillin, and the plasmid DNA is isolated by alkaline minilysis (J. Sambrook et al. 1989, 1.25 to 1.28), digested with SmaI and SstI, and fractionated by gel electrophoresis. A plasmid which contains a 1.4 kb SmaI/SstI fragment is designated pPS1 (see FIG. 3B).

The plasmid pPS72.2 is cleaved with SmaI and the 1.45 kb SmaI fragment is isolated. SmaI-linearized, dephosphorylated vector pUC18 is obtained from Boehringer Mannheim, Germany. 1 .mu.g each of the isolated 1.45 kb SmaI fragment from pPS72.2 and the SmaI-linearized, dephosphorylated vector pUC18 are joined by T4 DNA ligase and transformed into competent E. coli DH5alpha cells. Plasmid DNA is isolated from resultant ampicillin-resistant clones, cut with EcoRI and fractionated by gel electrophoresis. A plasmid possessing a 0.4 kb EcoRI fragment is designated pSab1 and contains the 1.45 kb SmaI fragment cloned in pUC18 in the orientation shown in FIG. 3B.

Plasmid pSab1 is digested with EcoRI. The resultant 3.7 kb fragment is isolated, religated with T4 DNA ligase, and transformed into E. coli DH5alpha. The 3.7 kb plasmid which is obtained is designated pSab3 (see FIG. 3B).

Plasmid pSab1 is cleaved with EcoRI, and the 0.4 kb EcoRI fragment is isolated, ligated with EcoRI-linearized, dephosphorylated vector pUC18, and transformed into competent E. coli DH5alpha cells. Ampicillin-resistant transformants containing plasmid DNA are isolated and cleaved with SmaI. A plasmid possessing a 0.4 kb SmaI fragment is designated pSab2.1 (see FIG. 3B). A plasmid containing a 3.1 kb SmaI fragment is designated pSab2.2 (see FIG. 3B).

9. Analysis of the DNA sequence of the 2.6 kb BamHI fragment from S. nodosus DSM40109

Following alkaline lysis, the plasmids pPS72.2, pPS1, pSab1, pSab2.1, pSab2.2 and pSab3 (see FIG. 3A and B) are purified by being subjected twice to cesium chloride density gradient centrifugation (see J. Sambrook et al., 1989, 1.38 to 1.43).

Two primers (pUC, sequencing and reverse-sequencing) are obtained from Boehringer, Mannheim, Germany. The other primers listed in Table 2 are synthesized as described in EP-A-0-368-224, Example 16. The sequences of the primers which were used for sequencing plasmids pPS72.2, pPS1, pSab1, pSab2.1, pSab2.2 and pSab3 are collated in Table 2.

The double-stranded DNA of the 2.6 kb BamHI fragment from S. nodosus DSM40109 was sequenced with the Promega fmol.TM. sequencing system (Serva, Heidelberg, Germany) using 6 .mu.Ci �.sup.35 S!-deoxyadenosine-5'-�alpha-thio!-triphosphate (1422 .mu.Ci/mmol) , DuPont de Nemours, NEN Division, Dreieich, Germany.

The so-called annealing temperature (TA), at which the respective primer binds to the template DNA, is listed in Table 2. Denaturation, primer-binding (annealing) and TaqI polymerase reaction (elongation) are carried out in a Perkin Elmer Cetus DNA Thermal Cycler, Bodenseewerk, Uberlingen, Germany. In this procedure, after heating at 95.degree. C. for 2 min, the temperature programs 1 (30 sec 95.degree. C., 30 sec T.sub.A, 1 min 70.degree. C.) or 2 (30 sec 95.degree. C., 30 sec., T.sub.A, 70.degree. C.) will pass through in 30 cycles in each case, as indicated in Table 2.

After adding stop solution (see fmol.TM. DNA sequencing system), the four sample mixtures are fractionated on a 6% polyacrylamide-urea gel. For this, the Macrophor sequencing chamber, Pharmacia Biosystems GmbH, Freiburg, Germany, is used. The glass plates are precleaned with absolute ethanol. The glass plate with the cut out is rubbed down with 8 ml of absolute alcohol to which is added 240 .mu.l of 10% acetic acid and 40 .mu.l of binding silane (Pharmacia). The thermoplate is treated with 5 ml of repellent silane (Pharmacia). Subsequently, each is then polished with absolute ethanol.

The 6% polyacrylamide-urea gel comprises 6% acrylamide/bisacrylamide (19:1), 7M urea in TBE �0.1M Tris, 89 mM boric acid, 1 mM EDTA (ethylenediaminetetra-acetate)!. 0.06% ammonium persulfate and 0.1% TEMED (N,N,N',N'-tetramethylethylenediamine) are added for the polymerization. Before pouring, the solution is filtered through a cellulose nitrate membrane (Nalgene.RTM. type S, pore diameter 0.2 .mu.m, Oskar Glock, Offenbach) and degassed.

The fractionation is carried out in TBE buffer at 60.degree. C. for 1.5 h or 3.5 h and at 2400 V. The gel is subsequently tilted for 10 min in 10% acetic acid, and then briefly rinsed with water and dried at 65.degree. C. for 30 min. Autoradiography is carried out at room temperature for 1 to 3 days using Kodak X-Omat.TM. XAR5 films in an exposure cassette equipped with intensifying screens (Dr. Goos Suprema Universal). The X-ray film is developed in a developing machine (Agfa Gevaert).

The DNA sequence of the 2634-kb BamHI fragment is depicted in FIG. 4. The DNA sequence (SEQ ID No. 3) which was obtained is translated into the corresponding amino acid sequence (SEQ ID Nos. 32, 33+34) from nucleotide positions Nos. 1 to 401. The codon usage in this segment (snoM gene segment) corresponds to the codon usage which is characteristic for Streptomycetes genes (F. Wright et al., 1992, gene 113:55-65). A stop codon (TGA) is present at nucleotide position No. 402. The identified open reading frame encompasses 133 amino acid residues. Comparison of this amino acid sequence with the EMBL database (TFASTA program of the database searching program of the GCG package, version 7, Genetics Computer Group Inc. Madison, Wis., USA) indicates 42 agreement with the C terminal part (amino acid positions Nos. 59 to 201) of the dTDP-4-keto-6-deoxy-D-glucose 3,5-epimerase (strM) of S. griseus DSM40236. On the basis of comparison of the biosynthesis pathways of dTDP-L-dihydrostreptose (FIG. 1) and dTDP-D-mycosamine (FIGS. 3 and 4.4), the snoM gene product is therefore designated dTDP-4-keto-6-deoxy-D-glucose 3,4-isomerase.

An additional open reading frame (snoT gene segment) is located from nucleotide positions Nos. 416 to 1532. The deduced amino acid sequence encompasses 372 residues. In the region of amino acid positions Nos. 259 to 340, there is 29% agreement with the corresponding part (amino acid positions Nos. 329 to 412) of the flavonol-O-3-glucosyl transferase of corn. For this reason, the snot gene product is designated amphotheronolide B-dTDP-mycosaminyl transferase.

An additional open reading frame (snoD gene segment) is located from nucleotide positions Nos. 1561 to 2625. The corresponding gene product (355 amino acid residues) possesses 54% sequence identity with the dTDP-D-glucose synthase from S. griseus DSM40236, and is therefore designated dTDP-D-glucose synthase (see FIG. 1 and FIGS. 3 and 4.4).
