How to specifically select a protein from one side of the membrane and to transport it on the other side ? That's what we will love to understand. #T6SS #T9SS

Quelle tristesse. Un grand monsieur et un ami qui s'en va ! Je me rappellerai longtemps de ta gentillesse, de ton humilité, et des conseils précieux. Toutes mes condoléances à Anne.
[HOMMAGE] Le CNRS a appris avec une grande tristesse le décès de Pierre Joliot, pionnier de la photosynthèse et figure de la recherche au CNRS. Nos condoléances à sa famille et à ses proches. 👉 insb.cnrs.fr/fr/cnrsinfo/hom…

How do bacteria build their flagella? We’ve put together an animation of Salmonella flagellum assembly based on cryo-EM and X-ray structures. From the membrane-embedded machinery to the growing filament, here’s how the parts come together, step-by-step.

When Pseudomonas is attacked, it strikes back! Outer membrane damage triggers a tit-for-tat T6SS retaliation via TagQ/TagR protein complex assembly, activating the PpkA kinase. Congrats to Maxim & team for uncovering this fascinating mechanism! nature.com/articles/s41467-0…

New study in @NAR_Open 🧬 A #T6SS-delivered Rhs toxin from Chromobacterium violaceum, TreThr, is an ADP-ribosyltransferase that selectively modifies charged tRNAThr(GGU), blocking ACC codon decoding & shutting down protein synthesis in rival bacteria. academic.oup.com/nar/article…

New in @CurrentBiology 🦠 Why do bacteria ditch their T6SS weapon? Experimental evolution shows that E. coli keeps it vs susceptible rivals, but loses it when facing immune ones. Great work @bTaillefer_ @JonasDesjardins! cell.com/current-biology/abs…

T2SS ? T4SS ? CDI ? T6SS ? T7SS ? NO ! The #T9SS is also involved in interbacterial competition !! @CurrentBiology Great work by Maelle Paillat @maelle_paillat under the supervision of Thierry Doan @doan_thierry sciencedirect.com/science/ar…
