Decreased nitrite reductase activity of deoxyhemoglobin correlates with platelet activation in hemoglobin E/ß-thalassemia subjects. [PDF]

open access: yesPLoS ONE, 2018
Nitric oxide (NO) can be generated from nitrite by reductase activity of deoxygenated hemoglobin (deoxyHb) apparently to facilitate tissue perfusion under hypoxic condition.

Bringing Nitric Oxide to the Molybdenum World—A Personal Perspective

open access: yesMolecules, 2023
Molybdenum-containing enzymes of the xanthine oxidase (XO) family are well known to catalyse oxygen atom transfer reactions, with the great majority of the characterised enzymes catalysing the insertion of an oxygen atom into the substrate. Although some

Regulation of Nitrite Reductase [PDF]

open access: yesPlant Physiology, 1987
A protein with molecular mass of 67 kilodaltons is immunoprecipitated from in vitro translated products obtained from rabbit reticulocyte lysate primed with polyadenylated RNA from nitrate treated illuminated pea seedlings. This protein resembles the native nitrite reductase because of its competitive elimination when immunoprecipitation of in vitro ...

Molecular underpinnings of nitrite effect on CymA-dependent respiration in Shewanella oneidensis

open access: yesFrontiers in Microbiology, 2016
Shewanella exhibit a remarkable versatility of respiration, with a diverse array of electron acceptors (EAs). In environments where these bacteria thrive, multiple EAs are usually present.

Nitrate Reductase Regulates Expression of Nitrite Uptake and Nitrite Reductase Activities in Chlamydomonas reinhardtii [PDF]

open access: yesPlant Physiology, 1992
In Chlamydomonas reinhardtii mutants defective at the structural locus for nitrate reductase (nit-1) or at loci for biosynthesis of the molybdopterin cofactor (nit-3, nit-4, or nit-5 and nit-6), both nitrite uptake and nitrite reductase activities were repressed in ammonium-grown cells and expressed at high amounts in nitrogen-free media or in media ...

Analysis of the Effects of Dietary Pattern on the Oral Microbiome of Elite Endurance Athletes [PDF]

open access: yes, 2019
Although the oral microbiota is known to play a crucial role in human health, there are few studies of diet x oral microbiota interactions, and none in elite athletes who may manipulate their intakes of macronutrients to achieve different metabolic ...

Synergistic Intra‐ and Inter‐Nanozyme Electron Transfer through Interfacial Assembly for Enhanced Multi‐Enzyme Activity

open access: yesAdvanced Science, EarlyView.
A novel Prussian blue‐based composite nanoenzymes (PB C‐NZs)‐MoS2/PB, was designed based on the electron transfer mechanism and transport pathway. The structure uses MoS2 as the substrate, with PB grown on its surface through a surface assembly method.

Protein complex formation during denitrification by Pseudomonas aeruginosa

open access: yesMicrobial Biotechnology, 2017
Summary The most efficient means of generating cellular energy is through aerobic respiration. Under anaerobic conditions, several prokaryotes can replace oxygen by nitrate as final electron acceptor.

Production of Nitric Oxide and Nitrosylleghemoglobin Complexes in Soybean Nodules in Response to Flooding

open access: yesMolecular Plant-Microbe Interactions, 2010
Nitric oxide (NO) has gained interest as a major signaling molecule during plant development and in response to environmental cues. Formation of NO during symbiotic interactions has been reported, but the role and sources of NO in nodules remain unclear.
