Snake venom phospholipase A2 (PLA2) that displays edema-inducing activities, as well as presynaptic neurotoxicity and low myotoxicity. 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 per subunit. Homodimer. Expressed by the venom gland. LD(50) is 1.2 mg/kg by intravenous injection into mice. Belongs to the phospholipase A2 family. Group II subfamily. D49 sub-subfamily. Ref.2 refers to only one protein (TMV-D49-PLA2), but erroneously shows two sequences. The translation of AF408409 (mentioned in Ref.2 as submitted to GenBank) differs by one amino acid from the sequence shown in Fig.1 and described in the text (see the conflict at position 71).
