SYSTEMATIC NAME
IUBMB Comments
ammonia:NAD+ oxidoreductase
An iron-sulfur flavoprotein (FAD) containing siroheme. This prokaryotic enzyme is specific for NADH. In addition to catalysing the 6-electron reduction of nitrite to ammonia, the enzyme from Escherichia coli can also catalyse the 2-electron reduction of hydroxylamine to ammonia. cf. EC 1.7.1.4, nitrite reductase [NAD(P)H].
