  • Bleomycin gene cluster components and their uses
    Patent number: 6927286
    Abstract: This invention provides detailed sequence analysis and characterization of the gene cluster responsible for the synthesis of bleomycin in Streptomyces verticillus. The bleomycin gene cluster provides the first hybrid polyketide synthase/nonribosomal peptide synthetase pathway and elucidation of the various modules and enzymatic domains characterizing the pathway provides convenient synthetic routes for bleomycins, bleomycin analogs, and various other polyketides.
