Snake venom phospholipase A2 (PLA2) that induces in vivo myotoxicity, moderates footpad edema, and causes in vitro neuromuscular blockade. 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. 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 35-45 degrees Celsius. Monomer. Expressed by the venom gland. Lys and Tyr residues play critical role in myotoxic, neurotoxic, and cytotoxic activities displayed by this toxin. In an other hand, His residues are relevant for edematogenic, neurotoxic, and myotoxic effects, but not for cytotoxic activity. Belongs to the phospholipase A2 family. Group II subfamily. D49 sub-subfamily.
