Nitrite dismutase

Nitrite dismutase (EC 1.7.6.1, Prolixin S, Nitrophorin 7) is an enzyme with systematic name nitrite:nitrite oxidoreductase.^[1]^[2] This enzyme catalyses the following chemical reaction

3 nitrite + 2 H⁺

\rightleftharpoons

2 nitric oxide + nitrate + H₂O

Nitrite dismutase ontains ferriheme b.
