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 dehydrogenase. [EC: 1.17.1.5]
Nicotinate + H(2)O + NADP(+) = 6-hydroxynicotinate + NADPH.
  • The enzyme is capable of acting on a variety of nicotinate analogs to varying degrees, including pyrazine-2-carboxylate, pyrazine 2,3- dicarboxylate, trigonelline and 6-methylnicotinate.
  • The enzyme from Clostridium barkeri also possesses a catalytically essential, labile selenium that can be removed by reaction with cyanide.
  • Forms part of the nicotinate-fermentation catabolism pathway in Eubacterium barkeri.
  • Other enzymes involved in this pathway are EC 1.3.7.1, EC 3.5.2.18, EC 1.1.1.291, EC 5.4.99.4, EC 5.3.3.6, EC 4.2.1.85 and EC 4.1.3.32.
  • Formerly EC 1.5.1.13.
