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 ...

Functional and evolutionary characterization of potential auxiliary metabolic genes of the global RNA virome

iMetaOmics, Volume 2, Issue 2, June 2025.
We generated the first comprehensive view of RNA viral auxiliary metabolic genes (AMGs), expanding the known functional type of AMGs by 75%. RNA viruses encode a remarkably high diversity of AMGs, spanning 25 distinct functional categories. Most of these genes are linked to environmental regulation and genetic information processing, with fewer ...

Microbial Ecology of Permafrost Soils: Populations, Processes, and Perspectives

Permafrost and Periglacial Processes, Volume 36, Issue 2, Page 245-258, April/June 2025.
ABSTRACT Permafrost microbial research has flourished in the past decades, due in part to improvements in sampling and molecular techniques, but also the increased focus on the permafrost greenhouse gas feedback to climate change and other ecological processes in high latitude and alpine permafrost soils.

Identification of iron(III) peroxo species in the active site of the superoxide reductase SOR from Desulfoarculus baarsii [PDF]

Journal of the American Chemical Society, American Chemical Society, 2002, pp.4966-7, 2015
The active site of superoxide reductase SOR consists of an Fe2+ center in an unusual [His4 Cys1] square-pyramidal geometry. It specifically reduces superoxide to produce H2O2. Here, we have reacted the SOR from Desulfoarculus baarsii directly with H2O2.

The Effect of Manure‐Based Fertilisers on Nitrogen Mineralisation and Greenhouse Gases Emissions After Soil Application

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 2, June 2025.
ABSTRACT The continuous increase of costs with mineral fertilisers made farmers search for alternatives, while livestock producers face strong challenges to, sustainably, manage large amount of manure. It is, therefore, important to provide strategies that could enhance the use of manures in agriculture, recycling nutrients and organic matter.

Analysis of Microbial Diversity Dominating Nitrite Enzymatic Degradation and Acidic Degradation in the Fermentation Broth of Northeast Sauerkraut

Foods
Nitrite hazard is an important food safety issue in the production process of Chinese Northeastern sauerkraut, but this nitrite can be eliminated through microbial enzymatic degradation and acidic degradation as fermentation progresses.

The regulation of glutamate dehydrogenase, nitrite reductase, and nitrate reductase in excised pea roots by nitrite

Biologia Plantarum, 1973
Both nitrite reductase and nitrate reductase were induced by nitrite, but there were differences in the time course of induction and in the response to different NO2 - concentrations between these enzymes. NH4 + depressed the induction of nitrite reductase. NADH2 dependent glutamate dehydrogenase activity was enhanced by those NO2-concentrations in the
