IntEnz Enzyme Nomenclature


Accepted name:
3-oxoacid CoA-transferase
Other names:
3-ketoacid CoA-transferase
3-ketoacid coenzyme A transferase
3-oxo-CoA transferase
3-oxoacid CoA dehydrogenase
3-oxoacid coenzyme A-transferase
acetoacetate succinyl-CoA transferase
acetoacetyl coenzyme A-succinic thiophorase
succinyl coenzyme A-acetoacetyl coenzyme A-transferase
succinyl-CoA transferase
succinyl-CoA:3-ketoacid-CoA transferase
Systematic name:
succinyl-CoA:3-oxo-acid CoA-transferase



Acetoacetate and, more slowly, 3-oxopropanoate, 3-oxopentanoate, 3-oxo-4-methylpentanoate or 3-oxohexanoate can act as acceptors; malonyl-CoA can act instead of succinyl-CoA.
