Ec Number:	1.7.6.1

Nitrite dismutase (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 contains ferriheme b.
