Nitrate Reductase mRNA Regulation in Nicotiana plumbaginifolia Nitrate Reductase-Deficient Mutants [PDF]
Light and substrate regulation of nitrate reductase (NR) expression were compared in wild type and mutant lines of Nicotiana plumbaginifolia. Mutants affected in the NR structural gene (nia) or in the biosynthesis of the NR molybdenum cofactor (cnx) were examined.

The biochemical comparison between two forms of nitrate reductase from cucumber roots: the soluble enzyme and the plasma membrane-associated one was made. Soluble nitrate reductase was purified on the blue-Sepharose 4B.

Extraction of nitrate reductase from members of the South African Proteaceae [PDF]
The inhibition of in vitro nitrate reductase activity in extracts of Protea spp. is shown to be due to polyphenolic constituents of the roots and shoots of the plants (which can be adsorbed by insoluble polyvinylpyrrolidone) rather than to the activity ...

Nitrate respiration in chemoautotrophic symbionts of the bivalve Lucinoma aequizonata [PDF]
Chemoautotrophic bacteria live symbiotically in gills of Lucinoma aequizonata, an infaunal clam inhabiting an oxygen-poor environment. These intracellular symbionts respire nitrate, i.e.

Complex formation between ferredoxin and Synechococcus ferredoxin:nitrate oxidoreductase [PDF]
The ferredoxin-dependent nitrate reductase from the cyanobacterium Synechococcus sp. PCC 7942 has been shown to form a high-affinity complex with ferredoxin at low ionic strength.

The production and detoxification of a potent cytotoxin, nitric oxide, by pathogenic enteric bacteria [PDF]
The nitrogen cycle is based on several redox reactions that are mainly accomplished by prokaryotic organisms, some archaea and a few eukaryotes, which use these reactions for assimilatory, dissimilatory or respiratory purposes.

Nitrate reductase catalyses the oxidation of NAD(P)H and the reduction of nitrate to nitrite. NR serves as a central point for the integration of metabolic pathways by governing the flux of reduced nitrogen through several regulatory mechanisms in plants,

The Arabidopsis NLP7 gene regulates nitrate signaling via NRT1.1-dependent pathway in the presence of ammonium. [PDF]
Nitrate is not only an important nutrient but also a signaling molecule for plants. A few of key molecular components involved in primary nitrate responses have been identified mainly by forward and reverse genetics as well as systems biology, however ...

Immunological comparison of the NADH:nitrate reductase from different cucumber tissues
Soluble nitrate reductase from cucumber roots (Cucumis sativus L.) was isolated and purified with blue-Sepharose 4B. Specific antibodies against the NR protein were raised by immunization of a goat.
