  • Patent number: 7452693
    Abstract: Genetic and biochemical characterization of the leinamycin biosynthesis gene cluster from Streptomyces atroolivaceus S-140 revealed two PKS genes, lnmI and lnmJ, that encode six PKS modules, none of which contains a cognate AT domain. The AT activity is provided in trans by a discrete protein, LnmG, which loads the malonyl coenzyme A extender unit onto the ACP domains of all six PKS modules. This finding provides a basis for methods of engineering modular polyketide synthases and polyketide synthase/nonribosomal peptide synthetases.
    Type: Grant
    Filed: October 18, 2006
    Date of Patent: November 18, 2008

  • Publication number: 20050080247
    Abstract: This invention provides detailed sequence analysis and characterization of the gene cluster responsible for the synthesis of leinamycin in Streptomyces atroolivaceus. The leinamycin gene cluster provides a hybrid polyketide synthase/nonribosomal peptide synthetase pathway. Elucidation of the various modules and enzymatic domains characterizing the pathway provides convenient synthetic routes for leinamycins, leinamycin analogs, and various other polyketides, peptides, and hybrid peptide-polyketide natural products.
