Phospholipase Cleavage Sites. Note that an enzyme that displays both PLA1 and PLA2 activities is called a Phospholipase B
A phospholipase is an enzyme that hydrolyzes phospholipids1 into fatty acids and other lipophilic substances. There are four major classes, termed A, B, C and D distinguished by what type of reaction they catalyze:
Types C and D are considered phosphodiesterases.
Phospolipase A2 acts on intact lecithin molecule and hydrolyses the fatty acid esterified to the second carbon atom.the product formed is lysolecithin and fatty acid. lysolecithin is an enzyme present in the venom of the viper snakes.2
