Snake venom Zinc metalloproteinase that inhibits ADP-induced platelet aggregation and inhibits the alpha-5/beta-1 (ITGA5/ITGB1) integrin, a fibronectin receptor. Has caseinolytic activity. Induces the detachment of cells that are bound to fibronectin. Binds 1 zinc ion per subunit. Inhibited by EDTA, and 1,10-phenanthroline. Dimer. Expressed by the venom gland. The N-terminus is blocked. Has no effect on alpha-2/beta-1 (ITGA2/ITGB1) integrin. Does not have hemorrhagic activity (PubMed:12893294). Belongs to the venom metalloproteinase (M12B) family. P-III subfamily. P-IIIc sub-subfamily. Gly-60 is present instead of the conserved His which is expected to be zinc-binding residue. There is therefore some uncertainty concerning the enzymatic activity of this protein.
