CC -!- FUNCTION: Hydrolyzes the sn-1 acylester bond of phospholipids.
CC Phosphatidylcholine, phosphatidylethanolamine and phosphatidic acid can
CC be used as substrates. Weak activity with lysophosphatidylcholine and
CC no activity with tripalmitoylglycerol and cholesteryl oleate. Seems to
CC have a preference for unsaturated fatty acids at the sn-1 position.
CC {ECO:0000269|PubMed:15355352}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 2-acyl-sn-
CC glycero-3-phosphocholine + a fatty acid + H(+); Xref=Rhea:RHEA:18689,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:28868,
CC ChEBI:CHEBI:57643, ChEBI:CHEBI:57875; EC=3.1.1.32;
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC pH dependence:
CC Optimum pH is 6.0-6.5. {ECO:0000269|PubMed:15355352};
CC Temperature dependence:
CC Optimum temperature is 60 to 65 degrees Celsius.
CC {ECO:0000269|PubMed:15355352};
CC -!- SUBCELLULAR LOCATION: Microsome membrane {ECO:0000269|PubMed:15355352};
CC Peripheral membrane protein {ECO:0000269|PubMed:15355352}.
CC -!- MISCELLANEOUS: Unaffected by calcium.
CC -!- SIMILARITY: Belongs to the AB hydrolase superfamily. Lipase family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAF01599.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
