Protein Domain : IPR009194

Type:  Family Name:  Adenosylcobalamin biosynthesis, ATP:cob(I)alamin adenosyltransferase, EutT-type
Description:  ATP:cob(I)alamin (or ATP:corrinoid) adenosyltransferases (), catalyse the conversion of cobalamin (vitamin B12) into its coenzyme form, adenosylcobalamin (AdoCbl)or coenzyme B12 []. AdoCbl contains an adenosyl moiety liganded to the cobalt ion of cobalamin via a covalent Co-C bond. AdoCbl is required as a cofactor for the activity of certain enzymes. ATP:cob(I)alamin adenosyltransferases are classed into three groups: CobA-type [], EutT-type [] and PduO-type []. Each of the three enzyme types appears to be specialised for particular AdoCbl-dependent enzymes or for the de novo synthesis AdoCbl. PduO and EutT are distantly related, sharing short conserved motifs, while CobA is evolutionarily unrelated and is an example of convergent evolution. This entry represents EutT-type ATP:cob(I)alamin adenosyltransferases, which are encoded by the ethanolamine utilization eut operon. They are believed to be specialised to support ethanolamine ammonia lyase, an AdoCbl-dependent enzyme that is part of the ethanolamine utilization pathway []. Bacteria that harbour the ethanolamine utilization pathway can use ethanolamine a source of carbon and nitrogen. Short Name:  AdoCbl_synth_CblAdoTrfase_EutT
