HHsearch alignment for GI: 254780934 and conserved domain: TIGR01651

>TIGR01651 CobT cobaltochelatase, CobT subunit; InterPro: IPR006538 These proteins are CobT subunits of the aerobic cobalt chelatase (aerobic cobalamin biosynthesis pathway). Pseudomonas denitrificans CobT has been experimentally characterised , . Aerobic cobalt chelatase consists of three subunits, CobT, CobN (IPR003672 from INTERPRO) and CobS (IPR006537 from INTERPRO). Cobalamin (vitamin B12) can be complexed with metal via the ATP-dependent reactions (aerobic pathway) (e.g., in Pseudomonas denitrificans) or via ATP-independent reactions (anaerobic pathway) (e.g., in Salmonella typhimurium) , . The corresponding cobalt chelatases are not homologous. However, aerobic cobalt chelatase subunits CobN and CobS are homologous to Mg-chelatase subunits BchH and BchI, respectively . CobT, too, has been found to be remotely related to the third subunit of Mg-chelatase, BchD (involved in bacteriochlorophyll synthesis, e.g., in Rhodobacter capsulatus) . Nomenclature note: CobT of the aerobic pathway Pseudomonas denitrificans is not a homolog of CobT of the anaerobic pathway (Salmonella typhimurium, Escherichia coli). Therefore, annotation of any members of this family as nicotinate-mononucleotide--5,6-dimethylbenzimidazole phosphoribosyltransferases is erroneous. .
