Nitrite accumulation during storage of tomato fruit as prevented by hydrogen gas

open access: yesInternational Journal of Food Properties, 2019
The adverse effects of intake nitrite upon human health are well known. However, eating fruits and vegetables is one of the main pathways to absorb nitrite because of nitrogen assimilation in plants.

Highly diverse nirK genes comprise two major clades that harbour ammonium-producing denitrifiers [PDF]

open access: yes, 2016
Background: Copper dependent nitrite reductase, NirK, catalyses the key step in denitrification, i.e. nitrite reduction to nitric oxide. Distinct structural NirK classes and phylogenetic clades of NirK-type denitrifiers have previously been observed ...

Anti-oxidant effect of nitrite in the pancreatic islets of type 2 diabetic male rats [PDF]

open access: yesIranian Journal of Basic Medical Sciences, 2023
Objective(s): Nitrite, a nitric oxide (NO) donor, increases insulin secretion from pancreatic islets and has positive metabolic effects in type 2 diabetes (T2D). Here, we test the hypothesis of whether nitrite-induced insulin secretion is due to blunting

Redox-coupled proton transfer mechanism in nitrite reductase revealed by femtosecond crystallography

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2016
Significance Copper nitrite reductase (CuNiR) is involved in denitrification of the nitrogen cycle. Synchrotron X-rays rapidly reduce copper sites and decompose the substrate complex structure, which has made crystallographic studies of CuNiR difficult ...

Distribution of Denitrification among Haloarchaea: A Comprehensive Study

open access: yesMicroorganisms, 2021
Microorganisms from the Halobacteria class, also known as haloarchaea, inhabit a wide range of ecosystems of which the main characteristic is the presence of high salt concentration.

Biotransformation of explosives by the old yellow enzyme family of flavoproteins [PDF]

open access: yes, 2004
Several independent studies of bacterial degradation of nitrate ester explosives have demonstrated the involvement of flavin-dependent oxidoreductases related to the old yellow enzyme (OYE) of yeast. Some of these enzymes also transform the nitroaromatic

Photolysis of n-butyl nitrite and isoamyl nitrite at 355 nm: A time-resolved Fourier transform infrared emission spectroscopy and ab initio study [PDF]

open access: yesJ. Chem. Phys. 130, 174314 (2009), 2009
We report on the photodissociation dynamics study of n-butyl nitrite (n-C_4H_9ONO) and isoamyl nitrite ((CH_3)_2C_3H_5ONO) by means of time-resolved Fourier transform infrared (TR-FTIR) emission spectroscopy. The obtained TR-FTIR emission spectra of the nascent NO fragments produced in the 355-nm laser photolysis of the two alkyl nitrite species showed

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

open access: yes, 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 ...
