Nitrite Oxidoreductase (NOR) is an enzyme catalysing the oxidation of nitrite and is located at the inner side of the cytoplasmic and intracytoplasmic membranes of Nitrobacter (Nb) species (1). NOR from N. hamburgenis (2) consist of at least two major subunits, alpha-NOR and beta-NOR, with molucular masses of approximately115 kDa and 65 kDa respectively.
The Nitrobacter species are gram-negative microorganism ubiquitos in nature and gain energy from the oxidation of nitrite to nitrate.
Nitrite Oxidoreductase purified from N. hamburgensis.
Alpha-subunit of NOR from N. hamburgenis K4, N. winogradskyi agilis K1, N winogradskyi 213, N. winogradskyi 215, N. winogradskyi 255, and n. vulgaris K48 (3).
Not determined
HYB 153-02 reacts well in Elisa coated with cell extract as well as immunoblotting with a band of approximately 115 kDa corresponding to the beta-subunit of NOR (3,4).
