Snake venom zinc metalloprotease that exhibits strong hemorrhagic activity. It also degrades alpha-chain of fibrinogen (FGA), but not the beta- and the gamma-chains. Possesses potent azocaseinolytic activity and cleaves insulin B-chain, hydrolyzing it at positions Ala(14)-Leu(15), followed by Tyr(16)-Leu(17) and His(10)-Leu(11). In vivo, subcutaneous injection into mice induces strong hemorrhage. Binds 1 zinc ion per subunit. Inhibited by EDTA, but not inhibited by iodoacetamide, PMSF and pepstatin A. Optimum pH is 7.5. Monomer. Expressed by the venom gland. The N-terminus is blocked. Glycosylated. Belongs to the venom metalloproteinase (M12B) family. P-III subfamily. P-IIIa sub-subfamily.
