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

open access: yesBio-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]

open access: yesJournal 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.

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

open access: yesPLoS 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

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

open access: yesFrontiers 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

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

open access: yesInternational 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.

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

open access: yesPlants, 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.

Molecular Screening of Nitrate Reductase Enzyme in Native Halophilic Bacteria of Iran [PDF]

open access: yesJournal of Cell and Molecular Research, 2021
With the increased usage of nitrate fertilizers, the removal of their stable ionic and water-soluble end products is a challenge for human health. Several physicochemical methods have been examined for nitrate removal of water, but biological treatments ...

Foliar Fertilization with Molybdate and Nitrate Up-Regulated Activity of Nitrate Reductase in Lemon Balm Leaves

open access: yesHorticulturae, 2023
The foliar feeding of soil-grown plants with essential elements such as molybdate can restore their Nitrate reductase activity. However, the activity of nitrate reductase under the foliar feeding of plants with molybdate and nitrate in hydroponic ...

Nitrate and periplasmic nitrate reductases [PDF]

open access: yesChem. Soc. Rev., 2014
The nitrate anion is a simple, abundant and relatively stable species, yet plays a significant role in global cycling of nitrogen, global climate change, and human health. Although it has been known for quite some time that nitrate is an important species environmentally, recent studies have identified potential medical applications.
