Accepted name: phospholipase A2
Reaction: phosphatidylcholine + H2O = 1-acylglycerophosphocholine + a carboxylate
Other name(s): lecithinase A; phosphatidase; phosphatidolipase; phospholipase A
Systematic name: phosphatidylcholine 2-acylhydrolase
Comments: Also acts on phosphatidylethanolamine, choline plasmalogen and phosphatides, removing the fatty acid attached to the 2-position. Requires Ca2+.
