| Enzyme Function | FUNCTION: Acts as a acyl-protein thioesterase hydrolyzing fatty acids from S-acylated cysteine residues in proteins such as trimeric G alpha proteins or HRAS (PubMed:9624183). Has depalmitoylating activity toward KCNMA1 (By similarity). Could also depalmitoylate ADRB2 (By similarity). Acts as a lysophospholipase hydrolyzing various lysophospholipids including lysophosphatidylcholine (lyso-PC), lysophosphatidylethanolamine (lyso-PE), lysophosphatidylinositol (lyso-PI) and lysophosphatidylserine (lyso-PS) (PubMed:8631810, PubMed:9644627). Has much higher thioesterase activity than lysophospholipase activity (By similarity). Contributes to the production of lysophosphatidic acid (LPA) during blood coagulation by recognizing and cleaving plasma phospholipids to generate lysophospholipids which in turn act as substrates for ENPP2 to produce LPA (By similarity). {ECO:0000250|UniProtKB:O75608, ECO:0000269|PubMed:8631810, ECO:0000269|PubMed:9624183, ECO:0000269|PubMed:9644627}. |
