A method is described for oxidatively decarboxylating a peptide, comprising combining a peptide with EpiD, wherein the peptide comprises at its carboxy terminus the amino acid sequence X.sub.1 X.sub.2 X.sub.3 X.sub.4 X.sub.5 X.sub.6 C, wherein X.sub.1, X.sub.2, X.sub.3 and X.sub.4 are any one of the twenty common amino acids, X.sub.5 is Tyr, Val, Met, Leu, Ile, Phe or Trp, and X.sub.6 is Cys, Ala, Ser, Val, or Thr, whereby the oxidative decarboxylation of the peptide occurs.

Oxidative decarboxylation of peptides catalyzed by flavoprotein EpiD

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.
