IntEnz Enzyme Nomenclature


Accepted name:
acetate CoA-transferase
Other names:
acetate coenzyme A-transferase
butyryl CoA:acetate CoA transferase
butyryl coenzyme A transferase
succinyl-CoA:acetate CoA transferase
acetyl-CoA:acetoacetate CoA transferase
Systematic name:
acyl-CoA:acetate CoA-transferase



The enzyme belongs to family I of CoA-transferases, which operate with a ping-pong kinetic mechanism. The reaction takes place in two half-reactions and involves the formation of a CoA thioester intermediate with a glutamate residue. Unlike EC, butyrate—acetoacetate CoA-transferase, this enzyme exhibits maximal activity using acetate as the CoA acceptor. Substrate range depends on the specific enzyme. Typical substrates include butanoyl-CoA and pentanoyl-CoA.
