IUBMB Enzyme Nomenclature


Accepted name: 3-oxoacid CoA-transferase

Reaction: succinyl-CoA + a 3-oxo acid = succinate + a 3-oxoacyl-CoA

Other names: 3-oxoacid coenzyme A-transferase; 3-ketoacid CoA-transferase; 3-ketoacid coenzyme A transferase; 3-oxo-CoA transferase; 3-oxoacid CoA dehydrogenase; acetoacetate succinyl-CoA transferase; acetoacetyl coenzyme A-succinic thiophorase; succinyl coenzyme A-acetoacetyl coenzyme A-transferase; succinyl-CoA transferase

Systematic name: succinyl-CoA:3-oxo-acid CoA-transferase

Comments: 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.
