Non-hemorrhagic metalloproteinase that hydrolyzes the alpha chains of fibrinogen and fibrin but has no activity on beta- and gamma-chains. Cleaves X-Leu bonds. Inhibits platelet aggregation induced by the von Willebrand factor (VWF) (IC(50) is 1.4 uM) and type I collagen (IC(50) is 3.2 uM). Acts by cleaving the vWF and its receptor GPIb, and by cleaving the collagen-binding Alpha-2A domain of the collagen receptor alpha-2/beta-1 integrin (ITGA2/ITGB1). Also degrades the extracellular matrix protein fibronectin (FN1), but has no effect on laminin and type I collagen. Binds 1 zinc ion per subunit. Monomer. Expressed by the venom gland. Belongs to the venom metalloproteinase (M12B) family. P-I subfamily.
