pfam12557: Co_AT_N (This model is not part of the current CDD release)
Cob(I)alamin adenosyltransferase N terminal
This domain family is found in bacteria and eukaryotes, and is approximately 20 amino acids in length. The family is found in association with pfam02572. Cob(I)alamin adenosyltransferase adenosylates Co(I) in an ATP-dependent manner in the conversion of aquacobalamin to its coenzyme form. This is the third step in this process, after two steps involved in the reduction of Co(III) to Co(I).
