  • Publication number: 20030027287
    Abstract: Recombinant DNA compounds that encode all or a portion of the oleandolide polyketide synthase are used to express recombinant polyketide synthase genes in host cells for the production of oleandolide, oleandolide derivatives, and polyketides that are useful as antibiotics and motilides.
    Type: Application
    Filed: March 14, 2001
    Publication date: February 6, 2003
    Inventors: Mary C. Betlach, Sanjay Krishnakant Shah, Robert McDaniel, Li Tang
  • Publication number: 20020002712
    Abstract: The present invention provides genetically altered plants and plant cells that have been modified to contain expression system(s) capable of expressing a functional polyketide synthase (PKS). The present invention further provides methods of producing PKS and polyketides using these plants and cells.
    Type: Application
    Filed: May 1, 2001
    Publication date: January 3, 2002
    Inventors: Mary C. Betlach, James T. Kealey, Neal Gutterson, Ed Ralston
  • Patent number: 6280999
    Abstract: Novel Sorangium polyketide synthases, and domains thereof, and polynucleotides encoding therefor. Additionally, chimeric polyketide synthases that include domains, or subsets of domains, patterned on said novel polyketide synthases. Methods to prepare polyketide combinatorial libraries are described, as are recombinant host cells in which polyketides are produced.
    Type: Grant

  • Patent number: 6251636
    Abstract: Recombinant DNA compounds that encode all or a portion of the oleandolide polyketide synthase are used to express recombinant polyketide synthase genes in host cells for the production of oleandolide, oleandolide derivatives, and polyketides that are useful as antibiotics and motilides.

    Inventors: Mary C. Betlach, Sanjay Krishnakant Shah, Robert McDaniel, Li Tang
  • Patent number: 6177262
    Abstract: Yields of polyketides produced in host cells such as Streptomyces can be increased by coexpression of the ptpA gene. The introduction of recombinant vectors encoding ptpA and polyketide synthase genes is more efficient and does not require methyl-free DNA if the host cell is a restriction/methylation deficient strain, such as Streptomyces lividans K4-114, K4-155, or K27-39.

    Inventors: Rainer Ziermann, Mary C. Betlach
  • Patent number: 6090601
    Abstract: Domains of epothilone polyketide synthase, and polynucleotides encoding therefor. Additionally, chimeric polyketide synthases that include domains, or subsets of domains, patterned on epothilone polyketide synthase. Methods to prepare epothilone in pharmaceutically useful quantitites are described, as are methods to prepare polyketide combinatorial libraries.

    Date of Patent: July 18, 2000
    Assignee: Kosan Bioscience
    Inventors: Claes Gustafsson, Mary C. Betlach
