Lysophospholipase

lysophospholipase d, lysophospholipase 2
In enzymology, a lysophospholipase EC 3115 is an enzyme that catalyzes the chemical reaction

2-lysophosphatidylcholine + H2O ⇌ glycerophosphocholine + a carboxylate

Thus, the two substrates of this enzyme are 2-lysophosphatidylcholine and H2O, whereas its two products are glycerophosphocholine and carboxylate

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds This family consists of lysophospholipase / phospholipase B EC 3115 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[1] Cytosolic phospholipase A2 associates with natural membranes in response to physiological increases in Ca2+ and selectively hydrolyses arachidonyl phospholipids,[2] the aligned region corresponds the carboxy-terminal Ca2+-independent catalytic domain of the protein as discussed in[2]

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

Examples

Human genes encoding proteins that contain this domain include:

  • PLA2G4A, PLA2G4B, PLA2G4C, PLA2G4D, PLA2G4E, PLA2G4F
