  • Biosynthetic process for the preparation of chemical compounds
    Patent number: 5843709
    Abstract: A bacterial host is described which is transformed by a plasmid coding for a polypeptide precursor wherein the host comprises a multi-enzyme complex capable of reacting with the expressed polypeptide precursor to produce a polypeptide comprising at least one dehydroamino acid and/or at least one lanthione bridge. A process for producing a polypeptide comprising at least one dehydroamino acid and/or at least one lanthione bridge, such as gallidermin, is also described. A plasmid capable of transforming a bacterial host is additionally described.Also disclosed are recombinant DNA molecules which specify Epi B, Epi C, Epi D, Epi P and Epi Q, enzymes which are involved in the biosynthesis of lantibiotic epidermin.
    Type: Grant
    Filed: June 6, 1995
    Date of Patent: December 1, 1998
    Assignee: Dr. Karl Thomae GmbH
    Inventors: Karl-Dieter Entian, Friedrich Gotz, Norbert Schnell, Johannes Augustin, Germar Engelke, Ralf Rosenstein, Cortina Kaletta, Cora Klein, Bernd Wieland, Thomas Kupke, Gunther Jung, Roland Kellner
