Rhizobium etli Produces Nitrous Oxide by Coupling the Assimilatory and Denitrification Pathways
Frontiers in Microbiology, 2019 More than two-thirds of the powerful greenhouse gas nitrous oxide (N2O) emissions from soils can be attributed to microbial denitrification and nitrification processes.

Nitrite Reductase Activity of Cytochrome c [PDF]
Journal of Biological Chemistry, 2008 Small increases in physiological nitrite concentrations have now been shown to mediate a number of biological responses, including hypoxic vasodilation, cytoprotection after ischemia/reperfusion, and regulation of gene and protein expression. Thus, while nitrite was until recently believed to be biologically inert, it is now recognized as a potentially

Genetic and environmental controls on nitrous oxide accumulation in lakes. [PDF]
PLoS ONE, 2015 We studied potential links between environmental factors, nitrous oxide (N2O) accumulation, and genetic indicators of nitrite and N2O reducing bacteria in 12 boreal lakes.

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

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.

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.

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.

Characterization of denitrifying activity by the alphaproteobacterium, Sphingomonas wittichii RW1
Frontiers in Microbiology, 2014 Sphingomonas wittichii RW1 has no reported denitrifying activity yet encodes nitrite and nitric oxide reductases. The aims of this study were to determine conditions under which S.
