Taxonomic identifier

90370 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Gammaproteobacteria › Enterobacteriales › Enterobacteriaceae › Salmonella

Protein attributes

Sequence length	202 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Converts N1-(5-phospho-alpha-D-ribosyl)-5,6-dimethylbenzimidazole into N1-alpha-D-ribosyl-5,6-dimethylbenzimidazole. Also catalyzes the conversion of adenosylcobalamin 5'-phosphate to adenosylcobalamin (vitamin B12); involved in the assembly of the nucleotide loop of cobalamin By similarity.
Catalytic activity	Adenosylcobalamin 5'-phosphate + H2O = coenzyme B12 + phosphate. Alpha-ribazole 5'-phosphate + H2O = alpha-ribazole + phosphate.
Pathway	Nucleoside biosynthesis; alpha-ribazole biosynthesis; alpha-ribazole from 5,6-dimethylbenzimidazole: step 2/2.
Sequence similarities	Belongs to the phosphoglycerate mutase family.
