"Purification and characterization of two highly different group II phospholipase A2 isozymes from a single viperid (Eristocophis macmahoni) venom.";
Eur. J. Biochem. 201:675-679(1991).

Comments

FUNCTION: PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides.
CATALYTIC ACTIVITY: Phosphatidylcholine + H₂O = 1-acylglycerophosphocholine + a carboxylate.
COFACTOR: Binds 1 calcium ion per subunit (By similarity).
SUBCELLULAR LOCATION: Secreted.
TISSUE SPECIFICITY: Expressed by the venom gland.
SIMILARITY: Belongs to the phospholipase A2 family. Group II subfamily.
