Enzyme Information
| 1.7.1.15 |
Nitrite reductase (NADH).
based on mapping to UniProt P0A9I8
Ammonia + 3 NAD(+) + 2 H(2)O = nitrite + 3 NADH.
-!- This prokaryotic enzyme is specific for NADH. -!- In addition to catalyzing the 6-electron reduction of nitrite to ammonia, the enzyme from Escherichia coli can also catalyze the 2-electron reduction of hydroxylamine to ammonia. -!- cf. EC 1.7.1.4.
