专利号:US-2004053274-A1 优先权日:2002-09-04 标 题 :Gene cluster of vicenistatin biosynthesis, a vicenisamine glycosyltransferase polypeptide, and a gene encoding the polypeptide 发明人:KAKINUMA KATSUMI 权利人:TOKYO INST TECH 摘要:To achieve enzymatic production of vicenistatin, a valuable compound, this invention provides enzymes involved in biosynthesis of vicenistatin and genes encoding the enzymes. This invention provides base sequence of the vin cluster which encodes enzyme complex responsible for biosynthesis of vicenistatin. This invention further provides a glycosyltransferase (VinC enzyme), which catalyzes production of vicenistatin using dTDP-vicenisamine as a substrate. Moreover, this invention provides a gene (vinC gene) encoding the enzyme. The VinC enzyme is useful for enzymatic synthesis of valuable compound vicenistatin. Furthermore, it is suggested that use of the VinC enzyme will enable development of novel polyketide glycosides.

专利号:US-6004787-A 优先权日:1991-01-17 标题:Method of directing biosynthesis of specific polyketides 发明人:KATZ LEONARD; DONADIO STEFANO; MCALPINE JAMES B 权利人:ABBOTT LAB 摘要:A method to produce novel polyketide structures by designing and introducing specified changes in the DNA governing the synthesis of the polyketide is disclosed. The biosynthesis of specific polyketide analogs is accomplished by genetic manipulation of a polyketide-producing microorganism by isolating a polyketide biosynthetic gene-containing DNA sequence, identifying enzymatic activities associated within the DNA sequence, introducing one or more specified changes into the DNA sequence which codes for one of the enzymatic activities which results in an altered DNA sequence, introducing the altered DNA sequence into the polyketide-producing microorganism to replace the original sequence, growing a culture of the altered microorganism under conditions suitable for the formation of the specific polyketide analog, and isolating the specific polyketide analog from the culture. The method is most useful when the segment of the chromosome modified is involved in an enzymatic activity associated with polyketide biosynthesis, particularly for manipulating polyketide synthase genes from Saccarharopolyspora or Streptomyces.

Nucleic acid sequences encoding a DELTA5-desaturase, nucleic acid sequences which hybridize thereto, DNA constructs comprising a DELTA5-desaturase gene, and recombinant host microorganism or animal expressing increased levels of a DELTA5-desaturase are described. Methods for desaturating a fatty acid at the DELTA5 position and for producing arachidonic acid by expressing increased levels of a DELTA5 desaturase are disclosed. Fatty acids, and oils containing them, which have been desaturated by a DELTA5-desaturase produced by recombinant host microorganisms or animals are provided. Pharmaceutical compositions, infant formulas or dietary supplements containing fatty acids which have been desaturated by a DELTA5-desaturase produced by a recombinant host microorganism or animal also are described.

A method of synthesizing a recombinant polyhydroxyalkanoate monomer synthase is also provided. These recombinant polyhydroxyalknoate synthases are derived from multifunctional fatty acid synthases or polyketide synthases and generate hydroxyacyl acids capable of polymerization by a polyhydroxyalknoate synthase.
专利号:US-6255092-B1 优先权日:1993-09-24 标题:Stereospecific alcohol dehydrogenase isolated from Candida parapsilosis, amino acid and DNA sequences therefor, and method of preparation thereof 发明人:KOJIMA TOMOKO; YAMAMOTO HIROAKI; KAWADA NAOKI; MATSUYAMA AKINOBU 权利人:DAICEL CHEM 摘要:The present invention provides a novel secondary alcohol dehydrogenase useful for the synthesis of optically active alcohol and DNA encoding said enzyme. A microorganism belonging to genus Candida was found to produce a novel secondary alcohol dehydrogenase with a high stereochemical specificity. Using said enzyme, optically active alcohols were prepared, and by cloning of DNA encoding said enzyme, the base sequence of said DNA was determined. By providing a novel secondary alcohol dehydrogenase with a high stereochemical specificity and the gene encoding said enzyme, an efficient production of optically active alcohols became possible.
