An integrated biochemical system for nitrate assimilation and nitric oxide detoxification in Bradyrhizobium japonicum [PDF]

, 2016
Rhizobia are recognized to establish N(2)-fixing symbiotic interactions with legume plants. Bradyrhizobium japonicum, the symbiont of soybeans, can denitrify and grow under free-living conditions with nitrate (NO(3)(−)) or nitrite (NO(2)(−)) as sole ...

Structure and evolution of chlorate reduction composite transposons. [PDF]

, 2013
UnlabelledThe genes for chlorate reduction in six bacterial strains were analyzed in order to gain insight into the metabolism. A newly isolated chlorate-reducing bacterium (Shewanella algae ACDC) and three previously isolated strains (Ideonella ...

The nitric oxide response in plant-associated endosymbiotic bacteria [PDF]

, 2011
Nitric oxide (NO) is a gaseous signalling molecule which becomes very toxic due to its ability to react with multiple cellular targets in biological systems. Bacterial cells protect against NO through the expression of enzymes that detoxify this molecule

Phyloecology of nitrate ammonifiers and their importance relative to denitrifiers in global terrestrial biomes

Nature Communications, 2023
Nitrate ammonification is important for soil nitrogen retention. However, the ecology of ammonifiers and their prevalence compared with denitrifiers, being competitors for nitrate, are overlooked.

Nitrite Generating and Depleting Capacity of the Oral Microbiome and Cardiometabolic Risk: Results from ORIGINS

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background The enterosalivary nitrate–nitrite–nitric oxide (NO3–NO2–NO) pathway generates NO following oral microbiota‐mediated production of salivary nitrite, potentially linking the oral microbiota to reduced cardiometabolic risk.

The key role of nitric oxide in hypoxia: hypoxic vasodilation and energy supply-demand matching [PDF]

, 2013
Significance: a mismatch between energy supply and demand induces tissue hypoxia with the potential to cause cell death and organ failure. Whenever arterial oxygen concentration is reduced, increases in blood flow - 'hypoxic vasodilation' - occur in an ...

Intramolecular Electron Transfer in Nitrite Reductases [PDF]

ChemPhysChem, 2005
AbstractThe copper‐ and heme‐containing nitrite reductases (NiRs) are key enzymes in denitrification. Their subunits contain two distinct redox‐active metal centers, an electron‐accepting site and a nitrite‐reducing site, to carry out the single‐electron reduction of nitrite to nitic oxide. Catalytic cycles of both enzyme families employ intramolecular

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

, 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 ...

Impact of mitochondria on nitrite metabolism in HL-1 cardiomyocytes

Frontiers in Physiology, 2013
Apart from ATP synthesis mitochondria have many other functions, one being nitrite reductase activity. NO released from nitrite has been shown to protect the heart from ischemia/reperfusion injury in a cGMP-dependent manner.
