CC   -!- FUNCTION: Snake venom phospholipase A2 (PLA2) that induces local edema
CC       a few hours after injection (5-10 ug) in the hind paw. PLA2 catalyzes
CC       the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-
CC       phosphoglycerides. {ECO:0000269|PubMed:12959640}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 1-acyl-sn-
CC         glycero-3-phosphocholine + a fatty acid + H(+); Xref=Rhea:RHEA:15801,

CC   -!- COFACTOR:
CC       Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000250};
CC       Note=Binds 1 Ca(2+) ion. {ECO:0000250};
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC   -!- PTM: Contains 7 disulfide bonds. {ECO:0000250}.
CC   -!- MASS SPECTROMETRY: Mass=13758; Method=Electrospray;
CC       Evidence={ECO:0000269|PubMed:12959640};
CC   -!- SIMILARITY: Belongs to the phospholipase A2 family. Group II subfamily.
CC       {ECO:0000305}.
