IUBMB Enzyme Nomenclature

EC 4.1.1.41

Accepted name: methylmalonyl-CoA decarboxylase

Reaction: (S)-methylmalonyl-CoA = propanoyl-CoA + CO2

Other name(s): propionyl-CoA carboxylase; propionyl coenzyme A carboxylase; methylmalonyl-coenzyme A decarboxylase; (S)-methylmalonyl-CoA carboxy-lyase; (S)-2-methyl-3-oxopropanoyl-CoA carboxy-lyase (incorrect)

Systematic name: (S)-methylmalonyl-CoA carboxy-lyase (propanoyl-CoA-forming)

Comments: The enzyme from Veillonella alcalescens is a biotinyl-protein, requires Na+ and acts as a sodium pump.
