CC -!- FUNCTION: Acyl-CoA thioesterases are a group of enzymes that catalyze
CC the hydrolysis of acyl-CoAs to the free fatty acid and coenzyme A
CC (CoASH), providing the potential to regulate intracellular levels of
CC acyl-CoAs, free fatty acids and CoASH. Has an acyl-CoA thioesterase
CC activity towards the long chain fatty acyl-CoA thioester palmitoyl-CoA
CC (hexadecanoyl-CoA; C16:0-CoA). Displays a substrate preference for
CC fatty acyl-CoAs with chain-lengths C12-C18.
CC {ECO:0000250|UniProtKB:Q68D91}.
