ENZYME entry: EC 2.1.3.1

Accepted Name
Methylmalonyl-CoA carboxytransferase.
Alternative Name(s)
Methylmalonyl-CoA carboxyltransferase.
Transcarboxylase.
Reaction catalysed
(S)-methylmalonyl-CoA + pyruvate <=> propanoyl-CoA + oxaloacetate
Cofactor(s)
Biotin; Cobalt cation; Zn(2+).
Comment(s)
  • A biotinyl-protein, containing cobalt and zinc.
  • The enzyme, described from the bacterium Propionibacterium shermanii, is unique among the biotin-dependent enzymes in that it catalyzes carboxyl transfer between two organic molecules, utilizing two separate carboxyltransferase domains.
  • The enzyme is a very large complex, consisting of a hexameric central core of 12S subunits surrounded by six 5S subunit dimers, each connected to the central core by twelve 1.3S biotin carrier subunits.
