Function

ACSS3 is part of a family known as Acyl-coenzyme A synthetases (ACSs), which catalyze the initial reaction in

fatty acid metabolism Fatty acid metabolism consists of various metabolic processes involving or closely related to fatty acids, a family of molecules classified within the lipid macronutrient category. These processes can mainly be divided into (1) catabolic processes ...

. This reaction activates fatty acids via thioesterification to CoA, thereby allowing their participation in both anabolic and catabolic pathways. The existence of many ACSs suggests that each plays a unique role, directing the acyl-CoA product to a specific metabolic fate. Knowing the full complement of ACS genes in the human genome will facilitate future studies to characterize their specific biological functions.
