EC Number | 3.1.2.2 |
Enzyme Function | FUNCTION: Catalyzes the hydrolysis of acyl-CoAs into free fatty acids and coenzyme A (CoASH), regulating their respective intracellular levels (PubMed:16940157, PubMed:10944470). Displays higher activity toward long chain acyl CoAs (C14-C20) (PubMed:16940157, PubMed:10944470). The enzyme is involved in enhancing the hepatic fatty acid oxidation in mitochondria (By similarity). {ECO:0000250|UniProtKB:Q9QYR9, ECO:0000269|PubMed:10944470, ECO:0000269|PubMed:16940157}. |
