In enzymology, a methylmalonyl-CoA carboxytransferase (EC 2.1.3.1) is an enzyme that catalyzes the chemical reaction

The enzyme can convert pyruvate to oxaloacetate, using (S)-methylmalonyl-CoA as its cofactor.[1][2][3]

This enzyme belongs to the family of transferases that transfer one-carbon groups, specifically the carboxy- and carbamoyltransferases. The systematic name of this enzyme class is (S)-methylmalonyl-CoA:pyruvate carboxytransferase. Other names in common use include transcarboxylase, methylmalonyl coenzyme A carboxyltransferase, methylmalonyl-CoA transcarboxylase, oxalacetic transcarboxylase, methylmalonyl-CoA carboxyltransferase, methylmalonyl-CoA carboxyltransferase, (S)-2-methyl-3-oxopropanoyl-CoA:pyruvate carboxyltransferase, (S)-2-methyl-3-oxopropanoyl-CoA:pyruvate carboxytransferase, and carboxytransferase [incorrect]. This enzyme participates in propanoate metabolism. It has 3 cofactors: zinc, Biotin, and Cobalt.
