Journal ArticleDOI
Existence of Abnormal Protein Aggregates in Healthy Escherichia coli Cells
TL;DR: The results led us to speculate that protein aggregates may function as a temporary "trash organelle" for cellular detoxification, and it was shown that the levels of reactive oxygen species and unfolded or misfolded proteins determine the Levels of Protein aggregates.
Journal ArticleDOI
The role of thiol oxidative stress response in heat-induced protein aggregate formation during thermotolerance in Bacillus subtilis.
Stephanie Runde,Stephanie Runde,Noël Molière,Noël Molière,Anja Heinz,Etienne Maisonneuve,Armgard Janczikowski,Alexander K. W. Elsholz,Ulf Gerth,Michael Hecker,Kürşad Turgay,Kürşad Turgay +11 more
TL;DR: It is demonstrated that the transcription factor Spx, a regulatory substrate of ClpXP, is critical for the prevention of protein aggregate formation because its regulon encodes redox chaperones, such as thioredoxin, required for protection against thiol‐specific oxidative stress.
Journal ArticleDOI
A microscope automated fluidic system to study bacterial processes in real time.
TL;DR: A novel hybrid micro fluidic device that combines a thin agar pad and a custom flow chamber that allows real time analysis of a broad array of biological processes such as growth, development and motility is designed.
Journal ArticleDOI
Remarkable Functional Convergence: Alarmone ppGpp Mediates Persistence by Activating Type I and II Toxin-Antitoxins.
Kenn Gerdes,Etienne Maisonneuve +1 more
TL;DR: It is demonstrated that the conserved GTPase Obg and the second messenger ppGpp mediate persistence by activation of a type I toxin-antitoxin module (hokB/sokB) in E. coli.
Journal ArticleDOI
YtfK activates the stringent response by triggering the alarmone synthetase SpoT in Escherichia coli.
Elsa Germain,Paul Guiraud,Deborah Byrne,Badreddine Douzi,Badreddine Douzi,Meriem Djendli,Etienne Maisonneuve +6 more
TL;DR: The protein YtfK promotes SpoT-dependent accumulation of (p)ppGpp and is required for activation of the stringent response during phosphate and fatty acid starvation, and the results indicate that YTFK can interact with SpoT.
