Snake venom zinc metalloprotease that possesses hemorrhagic activity (minimum hemorrhagic dose, MHD=4.7 ug) when injected intradermally into mice. Degrades the alpha-chain of fibrinogen (FGA). Binds 1 zinc ion per subunit. Inhibited by ethylenediaminetetraacetic acid (EDTA) and 1,10-phenanthroline. Not inhibited by tosyl-L-lysine chloromethyl ketone (TCLK) and phenylmethanesulfonylfluoride (PMSF). Optimum pH is 7-9. Activity is stable between 20-40 degrees Celsius, decreases at higher temperatures and is lost at 70 degrees Celsius. Monomer. Expressed by the venom gland. Belongs to the venom metalloproteinase (M12B) family. P-III subfamily.
