Group IB phospholipase A2,phosphatidylcholine 2-acylhydrolase 1B,phospholipase A2,phospholipase A2, group IB (pancreas),PLA2,PLA2A,PPLA2.
PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides, this releases glycerophospholipids and arachidonic acid that serve as the precursors of signal molecules.
