Snake venom phospholipase A2 (PLA2) that shows strong anticoagulant activity. Binds directly with the coagulation factor FXa (F10) and blocks the formation of the prothombinase complex. Acts by a nonenzymatic mechanism (PubMed:10462445). Also inhibits the complex composed of tissue factor (F3) and coagulation factor VIIa (F7) (TF-VIIa complex) by both enzymatic and nonenzymatic mechanisms (PubMed:8866616). PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 1-acyl-sn-glycero-3-phosphocholine + a fatty acid + H(+) Binds 1 Ca(2+) ion. Expressed by the venom gland. LD(50) is 0.63 mg/kg by intravenous injection. Does not bind to coagulation factor FVa (F5) or prothrombin. Belongs to the phospholipase A2 family. Group I subfamily. D49 sub-subfamily.
