The metalloproteinase is a probable venom zinc protease that induces local hemorrhage in the skin of rats. Degrades type-IV collagen, gelatin, laminin and fibronectin. Has fibrinolytic activities. Has high hemagglutinating activity on red blood cells. Cleaves insulin B chain at 29-His-|-Leu-30, and 38-Ala-|-Leu-39 bonds (PubMed:8087204). Binds 1 zinc ion per subunit. Inhibited by 1,10-phenanthroline and EDTA. Monomer. Expressed by the venom gland. Belongs to the venom metalloproteinase (M12B) family.
