    Type: Grant
    Filed: April 28, 2000
    Date of Patent: June 25, 2002
    Assignee: Kosan Biosciences, Inc.
    Inventors: Bryan Julien, Leonard Katz, Chaitan Khosla
  • Recombinant methods and materials for producing epothilones C and D
    Patent number: 6303342
    Abstract: Recombinant nucleic acids that encode all or a portion of the epothilone polyketide synthase (PKS) are used to express recombinant PKS genes in host cells for the production of epothilones, epothilone derivatives, and polyketides that are useful as cancer chemotherapeutics, fungicides, and immunosuppressants.
    Type: Grant

    Inventors: Bryan Julien, Leonard Katz, Chaitan Khosla, Li Tang
  • Production of polyketides in bacteria and yeast
    Patent number: 6258566
    Abstract: Hybrid and novel polyketide synthases (PKSs) and polyketides are produced by use of a multiple vector system. The combinatorial possibilities offered by placing the various catalytic activities of PKS systems on separate vectors permits the construction of improved libraries of PKS and polyketides. In addition, polyketides can be produced in hosts that ordinarily do not produce polyketides by supplying, along with an expression system for the desired PKS, an expression system for holo acyl carrier protein (ACP) synthase.
