Snake venom zinc metalloprotease that has potent hemorrhagic activity, fibrinogenolytic activity on the alpha-subunit of human fibrinogen (FGA) in vitro and provokes necrosis in skin, muscle and lung tissues. May contribute to local edema and ecchymosis induced by venom. Hydrolyzes model substrate (beta-chain of insulin) at Ala(14)-Leu(15). Binds 1 zinc ion per subunit. Inhibited by 1,10-phenanthroline. Monomer. Expressed by the venom gland. Contains 9 disulfide bonds. Belongs to the venom metalloproteinase (M12B) family. P-III subfamily. P-IIIa sub-subfamily.
