ABSTRACT:
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.
