The molybdenum-containing enzyme nitrite oxidoreductase catalyzes the oxidation of nitrite to nitrate: NO − 2 + H 2 O → NO − 3 + 2 H + Reduction. The heme-based enzyme nitrite reductase catalyzes the conversion of nitrite to ammonia. The cycle begins with reduction of an iron-nitrite complex to a metal nitrosyl complex.
