FunFam 39690: Nitrate reductase, beta subunit

There are 2 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
Nitrate reductase. [EC: 1.7.99.4]
Nitrite + acceptor = nitrate + reduced acceptor.
  • The Pseudomonas enzyme is a cytochrome, but the enzyme from Micrococcus halodenitrificans is an iron protein containing molybdenum.
  • Reduced benzyl viologen and other dyes bring about the reduction of nitrate.

Selenate reductase. [EC: 1.97.1.9]
Selenite + H(2)O + acceptor = selenate + reduced acceptor.
  • The periplasmic enzyme from Thauera selenatis is a complex comprising three heterologous subunits (alpha, beta and gamma).
  • Nitrate, nitrite, chlorate and sulfate are not substrates.
  • A number of compounds, including acetate, lactate, pyruvate, and certain sugars, amino acids, fatty acids, di- and tricarboxylic acids, and benzoate can serve as electron donors.
