Nitrate Reductase mRNA Regulation in Nicotiana plumbaginifolia Nitrate Reductase-Deficient Mutants [PDF]

The Plant Cell, 1989
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.

Migraines Are Correlated with Higher Levels of Nitrate-, Nitrite-, and Nitric Oxide-Reducing Oral Microbes in the American Gut Project Cohort

mSystems, 2016
Nitrates, such as cardiac therapeutics and food additives, are common headache triggers, with nitric oxide playing an important role. Facultative anaerobic bacteria in the oral cavity may contribute migraine-triggering levels of nitric oxide through the ...

A Crp-dependent two-component system regulates nitrate and nitrite respiration in Shewanella oneidensis. [PDF]

PLoS ONE, 2012
We have previously illustrated the nitrate/nitrite respiratory pathway of Shewanella oneidensis, which is renowned for its remarkable versatility in respiration.

Exploring the Denitrification Proteome of Paracoccus denitrificans PD1222

Frontiers in Microbiology, 2018
Denitrification is a respiratory process that produces nitrous oxide as an intermediate, which may escape to the atmosphere before its reduction to dinitrogen through the nitrous oxide reductase NosZ. In this work, the denitrification process carried out

Frequency of Tongue Cleaning Impacts the Human Tongue Microbiome Composition and Enterosalivary Circulation of Nitrate

Frontiers in Cellular and Infection Microbiology, 2019
The oral microbiome has the potential to provide an important symbiotic function in human blood pressure physiology by contributing to the generation of nitric oxide (NO), an essential cardiovascular signaling molecule.

Comparative modelling and molecular docking of nitrate reductase from Bacillus weihenstephanensis (DS45)

Journal of Taibah University for Science, 2016
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,

Nitrate partially inhibits lipopolysaccharide-induced inflammation by maintaining mitochondrial function

Journal of International Medical Research, 2020
Objective Nitrate has been reported to protect cells via the nitrate-nitrite-nitric oxide (NO) pathway. Most studies tend to use nitrite to investigate the mechanisms of this pathway.

On The Regulation of Spinach Nitrate Reductase [PDF]

Plant Physiology, 1990
A coupled assay has been worked out to study spinach (Spinacea oleracea L.) nitrate reductase under low, more physiological concentrations of NADH. In this assay the reduction of nitrate is coupled to the oxidation of malate catalyzed by spinach NAD-malate dehydrogenase.

Nitrate Metabolism Modulates Biosynthesis of Biofilm Components in Uropathogenic Escherichia coli and Acts as a Fitness Factor During Experimental Urinary Tract Infection

Frontiers in Microbiology, 2020
To successfully colonize a variety of environments, bacteria can coordinate complex collective behaviors such as biofilm formation. To thrive in oxygen limited niches, bacteria’s versatile physiology enables the utilization of alternative electron ...

Phylogenetic and metabolic diversity of microbial communities performing anaerobic ammonium and methane oxidations under different nitrogen loadings

ISME Communications, 2023
The microbial guild coupling anammox and nitrite/nitrate-dependent anaerobic methane oxidation (n-DAMO) is an innovative process to achieve energy-efficient nitrogen removal with the beneficial use of methane in biogas or in anaerobically treated ...
