Phosphoribosyltransferase; This family of proteins represent the nicotinate-nucleotide- dimethylbenzimidazole phosphoribosyltransferase (NN:DBI PRT) enzymes involved in dimethylbenzimidazole synthesis. This function is essential to de novo cobalamin (vitamin B12) production in bacteria. Nicotinate mononucleotide (NaMN):5,6-dimethylbenzimidazole (DMB) phosphoribosyltransferase (CobT) from Salmonella enterica plays a central role in the synthesis of alpha-ribazole-5'-phosphate, an intermediate for the lower ligand of cobalamin.

Nicotinate-nucleotide-dimethylbenzimidazole phosphoribosyltransferase (DMB-PRT), also called CobT; Nicotinate-nucleotide-dimethylbenzimidazole phosphoribosyltransferase (DMB-PRT/CobT, not to be confused with the CobT subunit of cobaltochelatase, which does not belong to this group) catalyzes the synthesis of alpha-ribazole-5'-phosphate, from nicotinate mononucleotide (NAMN) and 5,6-dimethylbenzimidazole (DMB). This function is essential to the anaerobic biosynthesis pathway of cobalamin (vitamin B12), which is the largest and most complex cofactor in a number of enzyme-catalyzed reactions in bacteria, archaea and eukaryotes. Only eubacteria and archaebacteria can synthesize vitamin B12; multicellular organisms have lost this ability during evolution. DMB-PRT/CobT works sequentially with CobC (a phosphatase) to couple the lower ligand of cobalamin to a ribosyl moiety. DMB is the most common lower ligand of cobamides; other lower ligands include adenine, 5-methoxybenzimidazole or phenol. It has been suggested that earlier metabolic or enzymatic steps may control which lower ligand is available to DMB-PRT/CobT. In Salmonella enterica, for example, the lower ligand is DMB under aerobic conditions and adenine or 2-methyladenine under anaerobic conditions. Salmonella enterica DMB-PRT/CobT is a homodimer with two active sites, each active site is comprised of residues from both monomers. This group includes two distinct subfamilies, one archaeal-like, the other comprised of bacterial sequences.

Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits

Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
