TL;DR: The transcriptomes of Bacillus subtilis exposed to a wide range of environmental and nutritional conditions that the organism might encounter in nature are reported, offering an initial understanding of why certain regulatory strategies may be favored during evolution of dynamic control systems.
Journal ArticleDOI
Molecular Architecture of the "Stressosome," a Signal Integration and Transduction Hub
Jon Marles-Wright,Tim Grant,Olivier Delumeau,Gijs van Duinen,Susan J. Firbank,Peter J. Lewis,James W. Murray,J.A. Newman,Maureen B. Quin,Paul R. Race,Alexis Rohou,Willem Tichelaar,Marin van Heel,Richard J. Lewis +13 more
TL;DR: It is suggested that the different sensory extensions respond to different signals, whereas the conserved domains in the core integrate the varied signals, and the architecture of the stressosome provides the potential for cooperativity.
Journal ArticleDOI
A supramolecular complex in the environmental stress signalling pathway of Bacillus subtilis
TL;DR: It is demonstrated that RsbS alone cannot act as an alternative partner for RsbT, but instead requires the presence of £bR to create a high molecular mass RsbR:RsbS complex (∼‼ 1 MDa) able to capture £bT.
Journal ArticleDOI
Genome-wide identification of genes directly regulated by the pleiotropic transcription factor Spx in Bacillus subtilis
Tatiana Rochat,Pierre Nicolas,Olivier Delumeau,Alžbeta Rabatinová,Jana Korelusová,Aurélie Leduc,Philippe Bessières,Etienne Dervyn,Libor Krásný,Philippe Noirot +9 more
TL;DR: The study globally characterized the Spx regulatory network, revealing its role in the basal expression of some genes and its complex interplay with other stress responses.
Journal ArticleDOI
Protein-Protein Interactions That Regulate the Energy Stress Activation of σB in Bacillus subtilis
TL;DR: It is concluded that the higher affinity of RsbW for RsbV than for sigma(B), rather than a difference in the concentrations ofRsbV and sigma (B), is the driving force that is responsible for the switch of Rs bW to unphosphorylated Rsb V.
