| EC Number | 3.1.1.- |
| Enzyme Function | FUNCTION: Hydrolyzes specifically phosphatidic acid (PA) to produce 2-acyl lysophosphatidic acid (LPA; a potent bioactive lipid mediator) and fatty acid (By similarity). Does not hydrolyze other phospholipids, like phosphatidylserine (PS), phosphatidylcholine (PC) and phosphatidylethanolamine (PE) or triacylglycerol (TG) (By similarity). {ECO:0000250|UniProtKB:Q8WWY8}. |
