show Brenda entry

EC number

2.8.3.9

Accepted name

butyrate—acetoacetate CoA-transferase

Reaction

butanoyl-CoA + acetoacetate = butanoate + acetoacetyl-CoA

Other name(s)

butyryl coenzyme A-acetoacetate coenzyme A-transferase, butyryl-CoA-acetoacetate CoA-transferase

Systematic name

butanoyl-CoA:acetoacetate CoA-transferase

CAS registry number

66231-37-6

Comment

Butanoate, acetoacetate and their CoA thioesters are the preferred substrates, but the enzyme also acts, more slowly, on the derivatives of a number of C₂ to C₆ monocarboxylic acids.
