| Enzyme Function | FUNCTION: Involved in the detoxification of xenobiotics and in the activation of ester and amide prodrugs. Hydrolyzes retinyl esters (PubMed:12230550). Hydrolyzes p-nitrophenyl butyrate (PNPB), triacylglycerol and monoacylglycerol. Shows higher activity against PNPB, a short-chain fatty acid ester, than against triolein, a long-chain fatty acid ester. Shows no detectable activity against diacylglycerol, cholesterol ester or phospholipids. May play a role in adipocyte lipolysis (By similarity). {ECO:0000250|UniProtKB:Q91WU0, ECO:0000269|PubMed:12230550}. |
