Snake venom phospholipase A2 (PLA2) that triggers a high neuromuscular toxicity in chick biventer cervicis preparations, but not in mouse phrenic nerve-diaphragm (PND) preparations, suggesting a selective neurotoxin activity towards birds (PubMed:28063838). Does not induce myotoxic, coagulant, anticoagulant, edema, and antibacterial activities (PubMed:28063838). PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides (PubMed:28063838). 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. Inhibited by divalent cations different from calcium ions (cadmium, magnesium, manganese, zinc), since they act as competitive antagonists of this cofactor. Optimum pH is 8.0. Optimum temperature is 37 degrees Celsius. Monomer. Expressed by the venom gland. Belongs to the phospholipase A2 family. Group II subfamily. D49 sub-subfamily.
