Abstract: The invention provides nucleic acid molecules comprising all or a part of a daptomycin biosynthetic gene cluster. The daptomycin biosynthetic gene cluster may be derived from Streptomyces, preferably from S. roseosporus. The invention also provides other nucleic acid molecules from S. roseosporus. The invention further provides polypeptides encoded by the nucleic acid molecules, antibodies that specifically bind to the polypeptides, and methods of using the nucleic acid molecules, polypeptides and antibodies to produce daptomycin and other compounds.

Abstract: Degenerate primers which hybridize with various classes of antibiotic biosynthesis genes were used to amplify fragments of DNA from soil and lichen extracts. Cloning and sequencing of the amplified products showed that these products included a variety of novel and previously uncharacterized antibiotic biosynthesis gene sequences, the products of which have the potential to be active as antibiotics, immunosuppressors, antitumor agents, etc.
