EC 4.1.1.94 Details

show Brenda entry

EC number

4.1.1.94

Accepted name

ethylmalonyl-CoA decarboxylase

Reaction

(S)-ethylmalonyl-CoA = butanoyl-CoA + CO₂

Systematic name

(S)-ethylmalonyl-CoA carboxy-lyase (butanoyl-CoA-forming)

Comment

The enzyme, which exists in all vertebrates, decarboxylates ethylmalonyl-CoA, a potentially toxic compound that is formed in low amounts by the activity of EC 6.4.1.2, acetyl-CoA carboxylase and EC 6.4.1.3, propanoyl-CoA carboxylase. It prefers the S isomer, and can decarboxylate (R)-ethylmalonyl-CoA with lower efficiency. cf. EC 7.2.4.1, (S)-methylmalonyl-CoA decarboxylase (sodium-transporting).
