Funkcija

Ovaj gen kodira enzim kob(I)jirinatna kiselina a, c-diamid-adenoziltransferaza, koji katalizira posljednji korak u pretvaranju vitamina B₁₂ u adenozilkobalamin (AdoCbl), vitamina B₁₂ koji sadrži koenzim za metilmalonil-CoA mutazu.^[7]

Klinički značaj

Mutacije u genu su uzrok metilmalonske acidurije zbog zavisnog vezanja vitamina B₁₂ sa komplementarnom grupom cblB.^[7]
