There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Nicotinate-nucleotide--dimethylbenzimidazole phosphoribosyltransferase. [EC: 2.4.2.21]
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.
