Electrochemistry and spectroelectrochemistry of iron porphyrins in the presence of nitrite [PDF]
, 2001 The reaction of nitrite with ferric and ferrous porphyrins was examined using visible, infrared and NMR spectroscopy. Solutions of either ferric or ferrous porphyrin were stable in the presence of nitrite, with only complexation reactions being observed.

CydDC-mediated reductant export in Escherichia coli controls the transcriptional wiring of energy metabolism and combats nitrosative stress [PDF]
, 2016 The glutathione/cysteine exporter CydDC maintains redox balance in Escherichia coli. A cydD mutant strain was used to probe the influence of CydDC upon reduced thiol export, gene expression, metabolic perturbations, intracellular pH homeostasis, and ...

The Mechanism of Nitrite Reductase
Journal of Computational ChemistryABSTRACT Cytochrome c nitrite reductase (CcNiR) activates nitrite and produces ammonia. It is one of several enzymes that use a redox‐active cofactor to perform its reaction. In this case, the cofactor has a heme with a lysine as the proximal ligand and a charged nearby arginine.

The existence and significance of a mitochondrial nitrite reductase
Redox Report, 2005 The physiological functions of nitric oxide (NO) are well established. The finding that the endothelium-derived relaxing factor (EDRF) is NO was totally unexpected. It was shown that NO is a reaction product of an enzymatically catalyzed, overall, 5-electron oxidation of guanidinium nitrogen from L-arginine followed by the release of the free radical ...

Optimizing germination and cultivation of edible halophytes using effluents from an IMTA system
Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Halophytes offer nature‐based solutions to food insecurity and soil degradation, while their integration into integrated multi‐trophic aquaculture (IMTA) systems promotes circular economy practices. This study aimed to optimize the germination and cultivation of edible halophytic species, namely Limbarda crithmoides, Suaeda vera and

A three-domain copper-nitrite reductase with a unique sensing loop
IUCrJ, 2019 Dissimilatory nitrite reductases are key enzymes in the denitrification pathway, reducing nitrite and leading to the production of gaseous products (NO, N2O and N2).

Mass Spectrometry Reviews, EarlyView.ABSTRACT Nitrooxidative stress, driven by excess reactive nitrogen species like peroxynitrite, contributes to the pathogenesis of many chronic diseases. Among its molecular footprints, 3‐nitrotyrosine (3NT) has emerged as a biologically relevant marker of protein nitration.

Journal of Taibah University for Science, 2016 Nitrate reductase catalyses the oxidation of NAD(P)H and the reduction of nitrate to nitrite. NR serves as a central point for the integration of metabolic pathways by governing the flux of reduced nitrogen through several regulatory mechanisms in plants,

Denitrification, activity of bacterial flocs, and growth of a filamentous bacterium in relation with the bulking of activated sludge [PDF]
, 1978 Activated sludge with poor settling characteristics is caught under the term "bulking" sludge. Various types of bulking activated sludge can be distinguished.1) Sludge containing an abundance of filamentous microorganisms.2) Sludge, characterized by ...
