Snake venom phospholipase A2 (PLA2) that shows weak anticoagulant activity. Is more catalytically active than the strong anticoagulant protein CM-IV found in this venom. Acts by inhibiting the complex composed of tissue factor (F3) and coagulation factor VIIa (F7) (TF-VIIa complex) by only enzymatic mechanism (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. Belongs to the phospholipase A2 family. Group I subfamily.
