Increased nitrite reductase activity of fetal versus adult ovine hemoglobin.
American Journal of Physiology. Heart and Circulatory Physiology, 2009 Growing evidence indicates that nitrite, NO2-, serves as a circulating reservoir of nitric oxide (NO) bioactivity that is activated during physiological and pathological hypoxia.

AGU Advances, Volume 6, Issue 2, April 2025.Abstract Carbon dioxide (CO2) removal (carbon dioxide removal (CDR)) that combines decreased greenhouse gas emissions with atmospheric CO2 reduction is needed to limit climate change. Enhanced rock weathering (ERW) of ground silicate minerals is an emerging CDR technology with the potential to decrease atmospheric CO2. However, there are few multi‐year

Infection and Immunity, 2009 The nitrate dissimilation pathway is important for anaerobic growth in Pseudomonas aeruginosa. In addition, this pathway contributes to P. aeruginosa virulence by using the nematode Caenorhabditis elegans as a model host, as well as biofilm formation and

Nitrate‐Driven Eutrophication Supports High Nitrous Oxide Production and Emission in Coastal Lagoons
Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 4, April 2025.Abstract Under current circumstances, coastal lagoons are net emitters of nitrous oxide (N2O) to the atmosphere. We hypothesize that widespread nitrogen‐driven coastal eutrophication will enhance N2O production and emissions from coastal lagoons. Here, we quantified spatial and temporal patterns of sediment‐water and water‐air N2O fluxes in three large

Identification of iron(III) peroxo species in the active site of the superoxide reductase SOR from Desulfoarculus baarsii [PDF]
Journal of the American Chemical Society, American Chemical
Society, 2002, pp.4966-7, 2015 The active site of superoxide reductase SOR consists of an Fe2+ center in an unusual [His4 Cys1] square-pyramidal geometry. It specifically reduces superoxide to produce H2O2. Here, we have reacted the SOR from Desulfoarculus baarsii directly with H2O2.

Biologia Plantarum, 1973 Both nitrite reductase and nitrate reductase were induced by nitrite, but there were differences in the time course of induction and in the response to different NO2 - concentrations between these enzymes. NH4 + depressed the induction of nitrite reductase. NADH2 dependent glutamate dehydrogenase activity was enhanced by those NO2-concentrations in the

Enzymatic function of hemoglobin as a nitrite reductase that produces NO under allosteric control.
Journal of Clinical Investigation, 2005 Hypoxic vasodilation is a fundamental, highly conserved physiological response that requires oxygen and/or pH sensing coupled to vasodilation. While this process was first characterized more than 80 years ago, the precise identity and mechanism of the ...

Molecular Ecology Resources, Volume 25, Issue 3, April 2025.ABSTRACT The ammonia monooxygenase subunit A (amoA) gene has been used to investigate the phylogenetic diversity, spatial distribution and activity of ammonia‐oxidising archaeal (AOA) and bacterial (AOB), which contribute significantly to the nitrogen cycle in various ecosystems. Amplicon sequencing of amoA is a widely used method; however, it produces
