| Accepted name: |
nitrite reductase (cytochrome; ammonia-forming) |
| Reaction: |
NH3 + 2 H2O + 6 ferricytochrome c = nitrite + 6 ferrocytochrome c + 7 H+ |
| Other name(s): |
cytochrome c nitrite reductase; multiheme nitrite reductase |
| Systematic name: |
ammonia:ferricytochrome-c oxidoreductase |
| Comments: |
Found as a multiheme cytochrome in many bacteria. The enzyme from Escherichia coli contains five hemes c and requires Ca2+. It also reduces nitric oxide and hydroxylamine to ammonia, and sulfite to sulfide. |
