|Nitrite reductase (cytochrome).|
|Nitrite reductase (cytochrome; NO-forming).|
|Pseudomonas cytochrome oxidase.|

|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.
