Nitrite reductase

Nitritreduktasen are enzymes in plants and bacteria; they play an important role in nitrogen assimilation of plants and the nitrate respiration in bacteria ( denitrification). Nitritreduktasen catalyze the reduction of nitrite (NO2 - ) and are among the oxidoreductases.

There are four classes of enzymes, the nitrite reductase are:

  • Occurring only in plant ferredoxin - Nitritreduktasen ( EC 1.7.7.1 ) in the ammonium (NH4 ) is formed:
  • Which occurs in bacterial cytochrome cd1 ( EC 1.7.2.1 ), is formed in the nitric oxide (NO):
  • Cytochrome c552 in bacteria ( EC 1.7.2.2 ), is formed in the formal ammonia ( NH3):
  • Nitrite reductase ( NADPH) in bacteria and some fungi ( EC 1.7.1.4 ), wherein the consumption of NADH or NADPH, ammonium hydroxide ( NH4OH ) is produced:
  • Oxidoreductase
  • Protein group
