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.

标题:Method of directing biosynthesis of specific polyketides

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.

标题:Metabolic engineering of polyhydroxyalkanoate monomer synthases
发明人：SHERMAN DAVID H; WILLIAMS MARK D; XUE YONGQUAN
权利人:UNIV MINNESOTA
摘要:A novel pathway for the synthesis of polyhydroxyalkanoate is provided. 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.

权利人:US AGRICULTURE; UNIV WASHINGTON
摘要:DNA sequences which function specifically in the synthesis of 2,4-diacetylphloroglucinol (Phl) are described. The sequences include phl genes which encode phl gene proteins and coding and regulatory sequences for production of Phl as well as sequences containing phl genes, which sequences have the capability of conferring or enhancing Phl biosynthetic capability in bacterial strains. The transformed strains are useful as biocontrol agents against fungal pathogens.

摘要:A method for controlling starch synthesis in tomatoes including providing a population of plants derived from interspecific crosses of Lycopersicon spp. with Lycopersicon esculentum genotypes, and selecting individuals of the population that each contain an allele of a gene that increases starch synthesis, the gene originating from the Lycopersicon spp.
