Reduced Activity of Nitrate Reductase Under Heavy Metal Cadmium Stress in Rice: An in silico Answer [PDF]

Frontiers in Plant Science, 2019
Cadmium is a well known toxic heavy metal, which has various detrimental effects on plant system. In plants an important enzyme involved in the production of nitric oxide, nitrate reductase, is also affected by cadmium toxicity. According to many studies

Isoform-Specific NO Synthesis by Arabidopsis thaliana Nitrate Reductase [PDF]

Plants, 2019
Nitrate reductase (NR) is important for higher land plants, as it catalyzes the rate-limiting step in the nitrate assimilation pathway, the two-electron reduction of nitrate to nitrite.

In vitro Nitrate Reductase Activity Assay of Mycolicibacterium smegmatis Crude Extract [PDF]

Bio-Protocol, 2021
Nitrate is one of the major inorganic nitrogen sources for microorganisms. Many bacterial and archaeal lineages can express cytoplasmic assimilatory nitrate reductase (NAS), which catalyzes the rate-limiting reduction of nitrate to nitrite in the nitrate

Aquatic Hyphomycete Taxonomic Relatedness Translates into Lower Genetic Divergence of the Nitrate Reductase Gene [PDF]

Journal of Fungi, 2021
Aquatic hyphomycetes are key microbial decomposers in freshwater that are capable of producing extracellular enzymes targeting complex molecules of leaf litter, thus, being crucial to nutrient cycling in these ecosystems.

Role of Nitrate Reductase in NO Production in Photosynthetic Eukaryotes. [PDF]

Plants (Basel), 2019
Nitric oxide is a gaseous secondary messenger that is critical for proper cell signaling and plant survival when exposed to stress. Nitric oxide (NO) synthesis in plants, under standard phototrophic oxygenic conditions, has long been a very controversial

Mycobacterium smegmatis does not display functional redundancy in nitrate reductase enzymes. [PDF]

PLoS ONE, 2021
Reduction of nitrate to nitrite in bacteria is an essential step in the nitrogen cycle, catalysed by a variety of nitrate reductase (NR) enzymes. The soil dweller, Mycobacterium smegmatis is able to assimilate nitrate and herein we set out to confirm the

The indica nitrate reductase gene OsNR2 allele enhances rice yield potential and nitrogen use efficiency. [PDF]

Nat Commun, 2019
The indica and japonica rice (Oryza sativa) subspecies differ in nitrate (NO3−) assimilation capacity and nitrogen (N) use efficiency (NUE). Here, we show that a major component of this difference is conferred by allelic variation at OsNR2, a gene ...

Resolving the contributions of the membrane-bound and periplasmic nitrate reductase systems to nitric oxide and nitrous oxide production in Salmonella enterica serovar Typhimurium [PDF]

Biochemical Journal, 2011
The production of cytotoxic nitric oxide (NO) and conversion into the neuropharmacological agent and potent greenhouse gas nitrous oxide (N2O) is linked with anoxic nitrate catabolism by Salmonella enterica serovar Typhimurium.

Exploration of Nitrate Reductase Metabolic Pathway in Corynebacterium pseudotuberculosis [PDF]

International Journal of Genomics, 2017
Based on the ability of nitrate reductase synthesis, Corynebacterium pseudotuberculosis is classified into two biovars: Ovis and Equi. Due to the presence of nitrate reductase, the Equi biovar can survive in absence of oxygen.
