Snake venom phospholipase A that has strong antimicrobial activity against the Gram-negative bacterium X.axonopodis. Antimicrobial activity is not abolished by EDTA or p-BPB and is therefore not strongly dependent on the enzymatic activity. 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. Optimum pH is 8.0. Optimum temperature is 40 degrees Celsius. This toxin consists of 2 subunits: acidic and basic. The acidic subunit is non-toxic, without enzymatic activity and comprises 3 peptides that are cross-linked by 7 disulfide bridges. The basic subunit is toxic, has phospholipase A2 activity and is composed of a single chain. Expressed by the venom gland. Belongs to the phospholipase A2 family. Group II subfamily. D49 sub-subfamily.
