FunFam 13489: Nicotinate dehydrogenase subunit A

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 (cytochrome). [EC: 1.17.2.1]
Nicotinate + a ferricytochrome + H(2)O = 6-hydroxynicotinate + a ferrocytochrome + 2 H(+).
  • This two-component enzyme from Pseudomonas belongs to the family of xanthine dehydrogenases, but differs from most other members of this family.
  • While most members contain an FAD cofactor, the large subunit of this enzyme contains three c-type cytochromes, enabling it to interact with the electron transfer chain, probably by delivering the electrons to a cytochrome oxidase.
