EC 3.1.1.111

Accepted name: phosphatidylserine sn-1 acylhydrolase

Reaction: (1) a phosphatidylserine + H2O = a 2-acyl-1-lyso-phosphatidylserine + a fatty acid
(2) a 1-acyl-2-lyso-phosphatidylserine + H2O = glycerophosphoserine + a fatty acid

Glossary: phosphatidylserine = 3-sn-phosphatidyl-L-serine = 1,2-diacyl-sn-glycero-3-phospho-L-serine
glycerophosphoserine = sn-glycero-3-phospho-L-serine

Other name(s): phosphatidylserine-specific phospholipase A1; PS-PLA1; PLA1A (gene name)

Systematic name: 3-sn-phosphatidyl-L-serine sn-1 acylhydrolase

Comments: The enzyme, which has been described from mammals, is specific for phosphatidylserine and 2-lysophosphatidylserine, and does not act on phosphatidylcholine, phosphatidylethanolamine, phosphatidic acid or phosphatidylinositol.
