In our effort to identify the proteolytic specificity of various hemorrhagic toxins isolated from western diamondback rattlesnake venom, hemorrhagic toxin b was isolated in homogeneous form by previously published methods. Hemorrhagic toxin b hydrolyzed glucagon, producing six fragments. The proteolytic sites were identified as Thr(5)-Phe(6), Thr(10)-Ser(11), Asp(15)-Ser(16), Asp(21)-Phe(22) and Try(25)-Leu(26). When oxidized insulin B chain was used, proteolysis occurred at four sites: Asn(3)-Gln(4), His(10)-Leu(11), Tyr(16)-Leu(17) and Gly(23)-Phe(24). The proteolytic specificity of hemorrhagic toxin b is quite different from those of the nonvenom proteases such as thermomycolin, aspergillopeptidase c, alkaline protease from Aspergillus flavus, elastase, subtilisin and papain.
