The sites of cleavage in oxidized insulin-B chain by a hemorrhagic protease derived from the venom of the habu (Trimeresurus flavoviridis).

The substrate specificity of a hemorrhagic protease derived from habu (Trimeresurus flavoviridis) venom was determined using oxidized insulin-B chain as a substrate. The enzyme was shown to be a fairly specific protease; it cleaved the substrate essentially at two positions, His10-Leu11 and Ala14-Leu15. The sites cleaved with the protease were compared to those reported with hemorrhagic proteases from other snake venoms.
