Enzyme Information
| 1.7.6.1 |
Nitrite dismutase.
based on mapping to UniProt Q94734
3 nitrite + 2 H(+) = 2 nitric oxide + nitrate + H(2)O.
-!- The enzyme is one of the nitrophorins from the salivary gland of the blood-feeding insect Rhodnius prolixus. -!- Nitric oxide produced induces vasodilation after injection. -!- Nitrophorins 2 and 4 can also catalyze this reaction.
