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

Function

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.

Clinical significance

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