Cob(I)alamin is the substrate of the enzyme ATP:cob(I)alamin adenosyltransferase (EC 2.5.1.17), that converts reduced cob(I)alamin to the adenosylcobalamin co-factor required for the functional activity of methylmalonyl-CoA mutase (EC 5.4.99.2). Mutations in the human MMAB gene result in a block in adenosylcobalamin synthesis and are responsible for the cblB complementation group of inherited vitamin B12 disorders, such as cobalamin malabsorption, which is an inborn error of metabolism. Vitamin B12 (cobalamin) is a complex cobalt-containing molecule that is essential to human health. It is synthesized in bacteria where it catalyzes numerous methyl transfer and intramolecular rearrangement reactions. In mammals, it is the co-factor of only two enzymes: methionine synthase, which catalyzes the transfer of a methyl group from methyltetrahydrofolate to homocysteine to form methionine, and methylmalonyl-CoA mutase, which catalyzes the rearrangement of methylmalonyl-CoA to form succinyl-CoA. For both enzymes, the vitamin must be modified through intracellular metabolism to co-factor forms: methylcobalamin (MeCbl)1 for methionine synthase and adenosylcobalamin (AdoCbl) for methylmalonyl-CoA mutase (PMID: 16439175).
