Synthetic and Evolutionary Construction of a Chlorate-Reducing Shewanella oneidensis MR-1. [PDF]

, 2015
UnlabelledDespite evidence for the prevalence of horizontal gene transfer of respiratory genes, little is known about how pathways functionally integrate within new hosts.

Exploring the Molecular Pathways Underlying the Anti‐Diabetic Effects of Millets

Food Safety and Health, EarlyView.
Millet consumption may modulate gluconeogenesis and glycolysis, enhance glucose transporter activity, increase leptin levels, inhibit the NF‐κB pathway, and mitigate oxidative and nitrosative stress. ABSTRACT Diabetes mellitus (DM) is a metabolic disorder characterized by hyperglycemic conditions resulting from inadequate insulin production or ...

A novel mechanism for dissimilatory nitrate reduction to ammonium in Acididesulfobacillus acetoxydans

mSystems
The biological route of nitrate reduction has important implications for the bioavailability of nitrogen within ecosystems. Nitrate reduction via nitrite, either to ammonium (ammonification) or to nitrous oxide or dinitrogen (denitrification), determines

Comparative modelling and molecular docking of nitrate reductase from Bacillus weihenstephanensis (DS45)

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,

Sampling of conformational ensemble for virtual screening using molecular dynamics simulations and normal mode analysis [PDF]

Future Medicinal Chemistry, 2015, 7 (17), pp.2317-2331, 2016
Aim: Molecular dynamics simulations and normal mode analysis are well-established approaches to generate receptor conformational ensembles (RCEs) for ligand docking and virtual screening. Here, we report new fast molecular dynamics-based and normal mode analysis-based protocols combined with conformational pocket classifications to efficiently generate

The relationship between redox enzyme activity and electrochemical potential—cellular and mechanistic implications from protein film electrochemistry [PDF]

, 2011
In protein film electrochemistry a redox protein of interest is studied as an electroactive film adsorbed on an electrode surface. For redox enzymes this configuration allows quantification of the relationship between catalytic activity and ...

The localization of nitrite reductase, glutamate synthase and malate metabolism enzymes in Pisum arvense L. roots

Acta Societatis Botanicorum Poloniae, 2014
Centrifugation of a homogenate made from Pisum arvense L. roots in a sucrose density gradient enabled the separation of the plastid fraction from mitochondria and microsomes.

Research Progress of Nitrite Metabolism in Fermented Meat Products

Foods, 2023
Nitrite is a common color and flavor enhancer in fermented meat products, but its secondary amines may transfer to the carcinogen N-nitrosamines. This review focuses on the sources, degradation, limitations, and alteration techniques of nitrite.

Discovery of superoxide reductase: an historical perspective [PDF]

Journal of Biological Inorganic Chemistry, 2004, 9, pp.119-23, 2014
For more than 30 years, the only enzymatic system known to catalyze the elimination of superoxide was superoxide dismutase, SOD. SOD has been found in almost all organisms living in the presence of oxygen, including some anaerobic bacteria, supporting the notion that superoxide is a key and general component of oxidative stress. Recently, a new concept

Trace metal requirements for microbial enzymes involved in the production and consumption of methane and nitrous oxide [PDF]

, 2012
Fluxes of greenhouse gases to the atmosphere are heavily influenced by microbiological activity. Microbial enzymes involved in the production and consumption of greenhouse gases often contain metal cofactors.
