Snake venom phospholipase A2 (PLA2) that shows anticoagulant activity and presynaptic neurotoxicity. Acts as an anticoagulant toxin by inhibiting prothrombinase complex formation. Shows about 50% of the prothrombinase complex inhibition compared to CM-IV of N.nigricollis venom. Acts as a neurotoxin by inhibiting neuromuscular transmission by blocking acetylcholine release from the nerve termini. 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. Monomer. Expressed by the venom gland. LD(50) is 0.18 mg/kg by intraperitoneal injection. Belongs to the phospholipase A2 family. Group II subfamily. D49 sub-subfamily.
