Cob(I)yrinic acid a,c-diamide adenosyltransferase, mitochondrial is an enzyme that in humans is encoded by the MMAB gene.[3][4][5]

Function[edit]

This gene encodes an enzyme (cob(I)yrinic acid a,c-diamide adenosyltransferase) that catalyzes the final step in the conversion of vitamin B12 into adenosylcobalamin (AdoCbl), a vitamin B12-containing coenzyme for methylmalonyl-CoA mutase.[5]

Clinical significance[edit]

Mutations in the gene are the cause of vitamin B12-dependent methylmalonic aciduria linked to the cblB complementation group.[5]
