Journal ArticleDOI
Analysis of the dynamic Bacillus subtilis Ser/Thr/Tyr phosphoproteome implicated in a wide variety of cellular processes.
Alain Levine,Françoise Vannier,Cédric Absalon,Lauriane Kuhn,Peter Jackson,Elaine Scrivener,Valérie Labas,Joëlle Vinh,Patrick Courtney,Jérôme Garin,Simone J. Séror +10 more
TL;DR: The nature of the Ser/Thr/Tyr phosphoproteome in Bacillus subtilis is established using in vivo labelling with [32P]‐orthophosphate, one‐unit pH 2‐DE, combined with MS, and significant changes to the profiles were obtained as a result of cold, heat or osmotic shock, demonstrating that, in stationary‐phase cells, the phosphoproteinome is dynamic.
Journal ArticleDOI
CpgA, EF-Tu and the stressosome protein YezB are substrates of the Ser/Thr kinase/phosphatase couple, PrkC/PrpC, in Bacillus subtilis.
Cédric Absalon,Michał Obuchowski,Edwige Madec,Delphine Delattre,I. Barry Holland,Simone J. Séror +5 more
TL;DR: It is proposed that the PrpC/PrkC/CpgA system constitutes an important element of a regulatory network involved in the coordination of cell wall expansion and growth in B. subtilis.
Journal ArticleDOI
Single-cell analysis in situ in a Bacillus subtilis swarming community identifies distinct spatially separated subpopulations differentially expressing hag (flagellin), including specialized swarmers.
Kassem Hamze,Sabine Autret,Krzysztof Hinc,Krzysztof Hinc,Soumaya Laalami,Daria Julkowska,Romain Briandet,Margareth Renault,Cédric Absalon,I. Barry Holland,Harald Putzer,Simone J. Séror +11 more
TL;DR: A model for this swarming process is discussed, emphasizing the importance of population density and of the complementary roles of packs of swarmers driving dendrite extension, while non-mobile cells in the stems extend dendrites by multiplication.
Journal ArticleDOI
The GTPase CpgA is implicated in the deposition of the peptidoglycan sacculus in Bacillus subtilis.
Cédric Absalon,Kassem Hamze,Didier Blanot,Claude Frehel,Rut Carballido-López,Barry Holland,Jean van Heijenoort,Simone J. Séror +7 more
TL;DR: Results are consistent with CpgA being involved in coordinating normal peptidoglycan deposition, and the inherent structure of the cell wall appeared mostly unchanged.
