SCIENCE – De la structure à la dynamique, une exploration fonctionnelle de la sécrétine XcpD de Pseudomonas aeruginosa.

Les bactéries ont développé d’ingénieux canaux membranaires, appelés sécrétines, spécifiquement adaptés à la sécrétion ou à l’assemblage de volumineuses macromolécules extracellulaires. L’organisation structurale des sécrétines est restée inconnue pendant plusieurs décennies, jusqu’à ce que les récents progrès de la cryo-microscopie électronique lèvent enfin le voile sur une organisation structurale atypique en double tonneau-beta géant cloisonné […]

SCIENCE – PatB is a transcriptional activator required for nitrogen fixation and cell differentiation in cyanobacteria.

Under nitrogen-limiting conditions, the filamentous cyanobacterium Nostoc PCC7120 differentiates nitrogen-fixing heterocysts at semi-regular intervals along filaments generating a periodic pattern of two distinct cell types. Heterocysts are micro-oxic cells that host the oxygen-sensitive nitrogenase allowing two antagonistic activities to take place simultaneously. Although several factors required to control the differentiation process are known, the molecular […]
COM – La vidéo d’animation illustrant les recherches menées au LCB est en ligne !

Lors de la refonte du site du laboratoire, une groupe de travail associant les étudiants du LCB a mené une réflexion sur la création d’une vidéo de médiation scientifique qui illustrerait les recherches menées dans nos locaux. Cette vidéo est a présent disponible et vous pouvez la visualiser ci-dessous. Compte tenu du public auquel elle […]

Come and discover our daily life as scientific investigators searching for new antioxidant mechanisms involved in cellular aging and the virulence of pathogenic bacteria. Our approaches : genetics, biochemistry, and […]
Summer internship in Galinier team

Study of a small regulatory RNA in Bacillus subtilis If you are interested in microbiology and in RNA, the Galinier team is proposing a voluntary internship this summer (June-July 2023) to study how a small regulatory RNA (sRNA) regulates sporulation and competence in the gram-positive bacteria Bacillus subtilis. The intern will use molecular biology and […]
