Phospholipase cleavage sites. An enzyme that displays both PLA1 and PLA2 activities is called a Phospholipase B.

A phospholipase is an enzyme that hydrolyzes phospholipids[1] into fatty acids and other lipophilic substances. There are four major classes, termed A, B, C and D, which are distinguished by the type of reaction which they catalyze:

Types C and D are considered phosphodiesterases.

Endothelial lipase is primarily a phospholipase.[2]

Phospholipase A2 acts on the intact lecithin molecule and hydrolyses the fatty acid esterified to the second carbon atom. The resulting products are lysolecithin and a fatty acid. Phospholipase A2 is an enzyme present in the venom of bees and viper snakes.[3]
