Enzyme Function FUNCTION: Snake venom phospholipase A2 (PLA2) that inhibits neuromuscular transmission by blocking acetylcholine release from the nerve termini and exhibits indirect hemolytic activity against human erythrocytes. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. {ECO:0000269|PubMed:14769867}.
