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.

Structural studies

As of late 2007, 12 structures have been solved for this class of enzymes, with PDB accession codes 1DCZ, 1DD2, 1ON3, 1ON9, 1RQB, 1RQE, 1RQH, 1RR2, 1S3H, 1U5J, 2D5D, and 2EVB.
