Cobalamin adenosyltransferase This family contains the gene products of PduO and EutT which are both cobalamin adenosyltransferases. PduO is a protein with ATP:cob(I)alamin adenosyltransferase activity. The main role of this protein is the conversion of inactive cobalamins to AdoCbl for 1,2-propanediol degradation [1].The EutT enzyme appears to be an adenosyl transferase, converting CNB12 to AdoB12 [2].
