Chains	Enzyme Name	Description	Catalytic Residues
A	phospholipase A2 (group group IVA) M-CSA #529	Cytosolic phospholipases A2 (cPLA2) are hydrolytic enzymes which catalyse the cleavage of the ester bond at the sn-2 position of phospholipid membranes to generate arachidonic acid, which is the precursor in the metabolic pathway of several lipid messengers, for instance, it is metabolised to prostaglandins by the cyclooxygenase pathway and to leukotrienes by the 5-lipooxygenase pathway. In addition, platelet-activating factor (PAF) can also be generated from a subset of the lysophospholipid produced.
