The anoxic plant mitochondrion as a nitrite: NO reductase

Mitochondrion, 2011
Under the conditions of oxygen deprivation, accumulating nitrite can be reduced in the mitochondrial electron transport chain forming free radical nitric oxide (NO). By reducing nitrite to NO, plant mitochondria preserve the capacity to oxidize external NADH and NADPH and retain a limited power for ATP synthesis complementing glycolytic ATP production.

Ferredoxin-nitrite reductase from spinach

Biochimica et Biophysica Acta (BBA) - Enzymology and Biological Oxidation, 1966
Summary 1. Nitrite reductase from a crude homogenate of spinach leaves has been purified about 500-fold and freed from NADP-reductase (EC 1.6.99.4) and nitrate reductase (EC 1.6.6.2). The enzyme, which does not seem to be a flavoprotein, catalyzes the reduction of nitrite to ammonia with a variety of enzyme systems as electron donors and requires

The induction of nitrite reductase in Neurospora crassa

Biochimica et Biophysica Acta (BBA) - General Subjects, 1972
Abstract Like nitrate reductase, nitrite reductase in Neurospora crassa is induced by either nitrate of nitrite and is repressed by ammonia. None of the enzymatic activities associated with the nitrite reductase, i.e. NADPH-nitrite reductase, reduced benzyl viologen-nitrite reductase or NADPH-hydroxylamine reductase, were derepressible when ...

On the Mechanism of Nitrite Reductase: Complex between Pseudoazurin and Nitrite Reductase from A. Cycloclastes

1998
Dissimilatory nitrite reductase is a trimeric copper-containing protein in Alcaligenes faecalis and Achromobacter cycloclastes. NO is the immediate product and is an intermediate in the dissimilatory denitrification pathway, in which nitrate is completely reduced to N2.

Studies on the Reductases of Nitrate and Nitrite

Journal of the agricultural chemical society of Japan, 1950
The fresh leaves of tobacco plants were ground and centrifuged. I can confirm the existence of a nitrate reductase in the supernatant fluid obtained. Nitrates eaten disappear in the tissues of silkworms. They are reduced to nitrites by the ground worm tissues.

[23] Ferredoxin-nitrite reductase

1980
Publisher Summary This chapter describes ferredoxin-nitrite reductase. Ferredoxin-nitrite reductase (EC 1.7.7.1) is the second enzyme component of the photosynthetic nitrate-reducing system. It was first identified as a ferredoxin-dependent chloroplast enzyme which catalyzes the 6-electron reduction of nitrite to ammonia.
