The enzyme lysophospholipase (EC 3.1.1.5) catalyzes the reaction
2-lysophosphatidylcholine + H2O formula_1 glycerophosphocholine + a carboxylate
This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. This family consists of lysophospholipase / phospholipase B (EC 3.1.1.5) and cytosolic phospholipase A2 which also has a C2 domain InterPro: "IPR000008". Phospholipase B enzymes catalyse the release of fatty acids from lysophospholipids and are capable "in vitro" of hydrolyzing all phospholipids extractable from yeast cells. Cytosolic phospholipase A2 associates with natural membranes in response to physiological increases in Ca2+ and selectively hydrolyses arachidonyl phospholipids, the aligned region corresponds the carboxy-terminal Ca2+-independent catalytic domain of the protein as discussed in.
The systematic name of this enzyme class is 2-lysophosphatidylcholine acylhydrolase. Other names in common use include lecithinase B, lysolecithinase, phospholipase B, lysophosphatidase, lecitholipase, phosphatidase B, lysophosphatidylcholine hydrolase, lysophospholipase A1, lysophopholipase L2, lysophospholipase transacylase, neuropathy target esterase, NTE, NTE-LysoPLA, and NTE-lysophospholipase. This enzyme participates in glycerophospholipid metabolism.
