Structure and mechanism of copper–carbonic anhydrase II: a nitrite reductase [PDF]

IUCrJ, 2020
Nitric oxide (NO) promotes vasodilation through the activation of guanylate cyclase, resulting in the relaxation of the smooth muscle vasculature and a subsequent decrease in blood pressure.

Kinetic Analysis of Nitrite Reduction Reactions by Nitrite Reductase Derived from Spinach in the Presence of One-Electron Reduced Riboflavin

Sci, 2022
The development of methods for converting nitrogen oxides in water into valuable resources such as ammonia and hydrazine has been given some attention. By utilizing the nitrite-reducing catalytic activity of nitrite reductase (NiR), nitrite in water can ...

Inheritance of nitrite reductase and regulation of nitrate reductase, nitrite reductase, and glutamine synthetase isozymes. [PDF]

Plant Physiology, 1984
Banding patterns of nitrate reductase (NR), nitrite reductase (NiR), and glutamine synthetase (GS) from leaves of diploid barley (Hordeum vulgare), tetraploid wheat (Triticum durum), hexaploid wheat (Triticum aestivum), and tetraploid wild oats (Avena barbata) were compared following starch gel electrophoresis.

Rhizobium etli is able to emit nitrous oxide by connecting assimilatory nitrate reduction with nitrite respiration in the bacteroids of common bean nodules

Journal of Plant Interactions, 2023
Legumes can contribute to emissions of the potent greenhouse gas nitrous oxide (N2O) directly by some rhizobia species that are able to denitrify under free-living conditions and in symbiotic association with the plant.

Nitrite‐reducing performance of two Lactobacillus strains isolated from traditional Sichuan fermented sausage in different production processes

Food Bioengineering, Volume 1, Issue 3-4, Page 307-318, December 2022., 2022
This study screened Pediococcus pentosaceus and Leuconostoc mesenteroides insects in traditional Sichuan sausages and determined their nitrite‐reducing properties during different production processes. These two strains are expected to be the starting point for the improvement of biological safety and nitrite residue control in traditional Sichuan ...

Responses of soil N-cycle enzyme activities to vegetation degradation in a wet meadow on the Qinghai-Tibet Plateau

Frontiers in Ecology and Evolution, 2023
Soil enzymes play a vital role in the functioning of wetland ecosystems, driving energy flow and material cycling processes. Gahai wet meadow, one of the important components of alpine wetlands on the Qinghai-Tibet Plateau, has suffered serious ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

Hepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

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
