IntEnz Enzyme Nomenclature


Accepted name:
succinyl-CoA:acetate CoA-transferase
Other names:
aarC (gene name)
Systematic name:
succinyl-CoA:acetate CoA-transferase



In acetic acid bacteria the enzyme, which is highly specific, catalyses the conversion of toxic acetate to acetyl-CoA [2,3]. In the hydrogenosomes of some trichomonads the enzyme catalyses the production of acetate [1].
