General Information

General Information	Comment	Organism
physiological function	in Salmonlella typhimurium, three types of corrinoid adenosyltransferases have been described. CoBa is a housekeeping enzyme involved in both the de novo biosynthesis and the salvage of adenosylcobalamin. The PduO adenosyl transferase is encoded in an operon (pdu) for cobalamin-dependent propanediol degradation and is induced by propanediol. Transferase EutT is encoded within the operon for ethanolamine utilization (eut). CobA produces sufficient Ado-B12 to initiate eut operon induction and to serve as a cofactor for EA-lyase when B12 levels are high. Once the eut operon is induced, the EutT transferase supplies more Ado-B12 during the period of high demand	Salmonella enterica subsp. enterica serovar Typhimurium
