HV-BBI--a novel amphibian skin Bowman-Birk-like trypsin inhibitor.

Abstract excerpt

Here we describe the isolation of a novel C-terminally amidated octadecapeptide--SVIGCWTKSIPPRPCFVK-amide--that contains a disulphide loop between Cys(5) and Cys(15) that is consistent with a Bowman-Birk type protease inhibitor, from the skin secretion of the Chinese Bamboo odorous frog, Huia versabilis. Named HV-BBI, the peptide is encoded by a single precursor of 62 amino acid residues whose primary structure...
