Enzyme Information
| 1.7.5.1 |
Nitrate reductase (quinone).
based on mapping to UniProt P11350
Nitrate + a quinol = nitrite + a quinone + H(2)O.
-!- A membrane-bound enzyme which supports anaerobic respiration on nitrate under anaerobic conditions and in the presence of nitrate Escherichia coli expresses two forms NarA and NarZ, both being comprised of three subunits.
