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]
