Nicotinate-nucleotide--dimethylbenzimidazole phosphoribosyltransferase.
based on mapping to UniProt Q05603
Beta-nicotinate D-ribonucleotide + 5,6-dimethylbenzimidazole = nicotinate + alpha-ribazole 5'-phosphate.
-!- Also acts on benzimidazole, and the clostridial enzyme acts on adenine to form 7-alpha-D-ribosyladenine 5'-phosphate. -!- The product of the reaction, alpha-ribazole 5'-phosphate, forms part of the corrin biosynthesis pathway and is a substrate for EC 2.7.8.2. -!- It can also be dephosphorylated to form alpha-ribazole by the action of EC 3.1.3.73.
