High resolution CryoEM structure of the ring-shaped virulence factor EspB from Mycobacterium tuberculosis

Stewart Cole, Florence Pojer, Jérémie Piton

The EspB protein of Mycobacterium tuberculosis is a 60 kDa virulence factor, implicated in conjugation and exported by the ESX-1 system of which it may also be a component. Previous attempts to obtain high-resolution maps of EspB by cryo-electron microscop ...

Microbiota-Derived Lactate Activates Production of Reactive Oxygen Species by the Intestinal NADPH Oxidase Nox and Shortens Drosophila Lifespan

Bruno Lemaitre, Jean Philippe Boquete, Igor Iatsenko

Commensal microbes colonize the gut epithelia of virtually all animals and provide several benefits to their hosts. Changes in commensal populations can lead to dysbiosis, which is associated with numerous pathologies and decreased lifespan. Peptidoglycan ...

Variability in DPA and calcium content in the spores of Clostridium species

Rizlan Bernier-Latmani, Barbora Bártová, Imrich Barak, Zuzana Chromiková, Cornelia List, Jan Jamroskovic

Spores of a number of clostridia' species, and their resistance to thermal treatment is a major concern for the food industry. Spore resistance to wet heat is related to the level of spore hydration, which is inversely correlated with the content of calciu ...
