ID 3.1.1.111 DE phosphatidylserine sn-1 acylhydrolase. AN phosphatidylserine-specific phospholipase A1. CA (1) a 1,2-diacyl-sn-glycero-3-phospho-L-serine + H2O = a 2-acyl- CA sn-glycero-3-phospho-L-serine + a fatty acid + H(+). CA (2) a 1-acyl-sn-glycero-3-phospho-L-serine + H2O = a fatty acid + H(+) + CA sn-glycero-3-phospho-L-serine. CC -!- The enzyme, which has described from mammals, is specific for CC phosphatidylserine and 2-lysophosphatidylserine, and does not act on CC phosphatidylcholine, phosphatidylethanolamine, phosphatidic acid or CC phosphatidylinositol.
