Snake venom zinc metalloprotease that possesses high hemorrhagic activity (minimum hemorrhagic dose (MHD)=0.82 ug) when subcutaneously injected into mice. May also potently degrade alpha chain of fibrinogen (FGA). Binds 1 zinc ion per subunit. Addition of Mg(2+) or Ca(2+) increases the casein hydrolysis rate. Monomer. Expressed by the venom gland. Belongs to the venom metalloproteinase (M12B) family. P-III subfamily. P-IIIa sub-subfamily.
