|Nitrite reductase (NO-forming).
|cd-cytochrome nitrite reductase.|
|Cytochrome c-551:O(2), NO(2)(+) oxidoreductase.|
|Hydroxylamine (acceptor) reductase.|
|Methyl viologen-nitrite reductase.|
|Nitrite reductase (cytochrome).|
|Nitrite reductase (cytochrome; NO-forming).|
|Pseudomonas cytochrome oxidase.|
|Nitric oxide + H(2)O + ferricytochrome c <=> nitrite + ferrocytochrome c + 2 H(+)|
|Cu cation or Fe cation; FAD.
- The reaction is catalyzed by two types of enzymes, found in the
perimplasm of denitrifying bacteria.
- One type comprises proteins containing multiple copper centers,
the other a heme protein, cytochrome cd1.
- Acceptors include c-type cytochromes such as cytochrome c-550 or
cytochrome c-551 from Paracoccus denitrificans or Pseudomonas
aeruginosa, and small blue copper proteins such as azurin and
- Cytochrome cd1 also has oxidase and hydroxylamine reductase
- May also catalyze the reaction of EC 22.214.171.124 since this is a well-
known activity of cytochrome cd1.
- Formerly EC 126.96.36.199, EC 188.8.131.52 and EC 184.108.40.206.
