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

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!

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.

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!

@_Wienman_ Yeah !!

Kudos to @NicolasRivard11 for creating this fantastic Cover illustration!
But… do do you recognize the original painting?
