Shows weak degradation of alpha-fibrinogen, but has no activity on beta- and gamma-chains. Digests luteinizing hormone-releasing hormone (LH-RH) and oxidized insulin at X-Leu, X-Phe, and X-Val bonds as well as X-His bond. Does not show fibrinogen-clotting activity. Does not show hemorrhagic activity. Inhibits ADP-induced platelet aggregation. Binds 1 zinc ion per subunit. The metalloproteinase is inhibited by EDTA, o-phenanthroline, and cysteine. Glutathione does not inhibit the enzymatic activity. Optimum pH is about 9. Homodimer; disulfide-linked (disintegrin). Expressed by the venom gland. The disintegrin belongs to the dimeric disintegrin subfamily. Belongs to the venom metalloproteinase (M12B) family. P-II subfamily. P-IId sub-subfamily.
