Snake venom zinc metalloproteinase that acts on fibrinogen, fibrin, fibronectin (FN1), type I collagen, type IV collagen, integrin alpha-7/beta-1 (ITGA7/ITGB1) and integrin alpha-1/beta-1 (ITGA1/ITGB1). Binds to fibronectin (FN1), fibrinogen and, weakly, to type I collagen and laminin. Cleaves Xaa-Leu bonds. Inhibits ADP- and collagen-induced platelet aggregation both in the presence (IC(50)=1.4 uM for collagen) and in the absence (IC(50)=2.2 uM for collagen) of cofactors. Has hemorrhagic activity. Binds 1 zinc ion per subunit. Inhibited by EDTA, DTT and high concentrations of zinc ions (>2 mM). Weakly inhibited by TLCK. Not inhibited by PMSF. Activated by calcium ions. Optimum pH is 7.5. Optimum temperature is 37 degrees Celsius. Monomer. Expressed by the venom gland. Does not cleave laminin-1 (laminin-111, LAMA1/LAMB1/LAMC1), integrin alpha-2/beta-1 (ITGA2/ITGB1) or integrin alpha-3/beta-1 (ITGA3/ITGB1). Belongs to the venom metalloproteinase (M12B) family. P-I subfamily.
