Catalyzes the hydrolysis of phosphatidylcholine with phospholipase A1 (EC 3.1.1.32) and phospholipase A2 (EC 3.1.1.4) activities. Shows hemolytic activity. a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 2-acyl-sn-glycero-3-phosphocholine + a fatty acid + H(+) a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 1-acyl-sn-glycero-3-phosphocholine + a fatty acid + H(+) Expressed by the venom gland. Causes an allergic reaction in human (By similarity). It exhibits some cross-reactivity with antibodies from mouse immunizated to other Hymenoptera phospholipases (PubMed:8828537). Belongs to the AB hydrolase superfamily. Lipase family.
