The HU Regulon Is Composed of Genes Responding to Anaerobiosis, Acid Stress, High Osmolarity and SOS Induction

PLoS ONE, 2009
Background The Escherichia coli heterodimeric HU protein is a small DNA-bending protein associated with the bacterial nucleoid. It can introduce negative supercoils into closed circular DNA in the presence of topoisomerase I.

Rice Seed Germination Underwater: Morpho-Physiological Responses and the Bases of Differential Expression of Alcoholic Fermentation Enzymes

Frontiers in Plant Science, 2017
The water-, energy-, and labor-intensive system of transplanted puddled rice (Oryza sativa) is steadily being replaced by direct seeding due to the progressive scarcity of these resources.

Oxygen Limitation Enhances the Antimicrobial Activity of Fosfomycin in Pseudomonas aeruginosa Following Overexpression of glpT Which Encodes Glycerol-3-Phosphate/Fosfomycin Symporter

Frontiers in Microbiology, 2018
Fosfomycin is resurfacing as a “last resort drug” to treat infections caused by multidrug resistant pathogens. This drug has a remarkable benefit in that its activity increases under oxygen-limited conditions unlike other commonly used antimicrobials ...

Quelques observations sur les conditions de la formation d'anhydride sulfureux en vinification

OENO One, 1985
Les formations importantes de SO2 en vinification en blanc dans les conditions de la pratique pourraient s'expliquer soit par l'intervention de levures particulières soit par des fermentations particulièrement lentes, à basses températures, dans des ...

The Role of the [2Fe‐2S] Cluster of Escherichia coli IscR in Responding to Redox‐Cycling Agents

Molecular Microbiology, EarlyView.
Redox cycling agents like phenazine methosulfate (PMS) are known for upsetting cellular redox balance. Here we describe how PMS leads to upregulation of the ISC and SUF Fe‐S cluster biogenesis pathways in Escherichia coli when PMS oxidizes the [2Fe‐2S]1+ cluster of the transcription factor IscR, thereby derepressing the operon encoding ISC and, when a ...

Crystal Structure of the Active Site Mutant Form of Soluble Fumarate Reductase, Osm1

Crystals, 2019
Soluble fumarate reductase is essential for survival under anaerobic conditions. This enzyme can maintain the redox balance in the cell by catalyzing the reduction of fumarate to succinate.
