CC -!- FUNCTION: Catalyzes the activation of medium/long-chain fatty acids as
CC acyl-coenzyme A (acyl-CoA), which are then transferred to the
CC multifunctional polyketide synthase (PKS) type III for further chain
CC extension. Also involved in the degradation of cholesterol via the
CC degradation of the side chains of C-24 branched-chain sterols.
CC Catalyzes the ATP-dependent CoA thioesterification of the sterol 3-
CC oxocholest-4-en-26-oate to yield 3-oxocholest-4-en-26-oyl-CoA.
CC {ECO:0000250|UniProtKB:P9WQ51}.
