Comments
Comment typeDescription
Biophysicochemical PropertiespH dependence: Optimum pH is 6.0-6.5. {ECO:0000269|PubMed:15355352}; Temperature dependence: Optimum temperature is 60 to 65 degrees Celsius. {ECO:0000269|PubMed:15355352};
Catalytic ActivityPhosphatidylcholine + H(2)O = 2- acylglycerophosphocholine + a carboxylate.
FunctionHydrolyzes the sn-1 acylester bond of phospholipids. Phosphatidylcholine, phosphatidylethanolamine and phosphatidic acid can be used as substrates. Weak activity with lysophosphatidylcholine and no activity with tripalmitoylglycerol and cholesteryl oleate. Seems to have a preference for unsaturated fatty acids at the sn-1 position. {ECO:0000269|PubMed:15355352}.
MiscellaneousUnaffected by calcium.
Sequence CautionSequence=AAF01599.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
SimilarityBelongs to the AB hydrolase superfamily. Lipase family. {ECO:0000305}.
Subcellular LocationMicrosome membrane {ECO:0000269|PubMed:15355352}; Peripheral membrane protein {ECO:0000269|PubMed:15355352}.
