KEGG   ENZYME: 1.7.2.1
Entry
EC 1.7.2.1                  Enzyme                                 

Name
nitrite reductase (NO-forming);
cd-cytochrome nitrite reductase;
[nitrite reductase (cytochrome)] [misleading, see comments.];
cytochrome c-551:O2, NO2+ oxidoreductase;
cytochrome cd;
cytochrome cd1;
hydroxylamine (acceptor) reductase;
methyl viologen-nitrite reductase;
nitrite reductase (cytochrome;
NO-forming)
Class
Oxidoreductases;
Acting on other nitrogenous compounds as donors;
With a cytochrome as acceptor
Sysname
nitric-oxide:ferricytochrome-c oxidoreductase
Reaction(IUBMB)
nitric oxide + H2O + ferricytochrome c = nitrite + ferrocytochrome c + 2 H+ [RN:R00783]
Reaction(KEGG)
R00783 > R00784;
(other) R00081 R00082 R00280 R00785
Substrate
nitric oxide [CPD:C00533];
H2O [CPD:C00001];
ferricytochrome c [CPD:C00125]
Product
nitrite [CPD:C00088];
ferrocytochrome c [CPD:C00126];
H+ [CPD:C00080]
Comment
The reaction is catalysed by two types of enzymes, found in the perimplasm of denitrifying bacteria. One type comprises proteins containing multiple copper centres, 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 pseudoazurin. Cytochrome cd1 also has oxidase and hydroxylamine reductase activities. May also catalyse the reaction of hydroxylamine reductase (EC 1.7.99.1) since this is a well-known activity of cytochrome cd1.
History
