Our paper on how a conveyor belt-associated protein of T9SS-driven gliding bacteria acts as a molecular switch, reversing T9SS rotation to fine-tune movement - like a smart conveyor or biological snowmobile adapting to changing terrain is out now in @mbio.bsky.social journals.asm.org/doi/10.1128/...
A molecular conveyor belt-associated protein controls the rotational direction of the bacterial type 9 secretion system | mBio
The type 9 secretion system (T9SS) is fundamental to bacterial gliding motility, pathogenesis,
and surface colonization. Our findings reveal that the C-terminal region of the conveyor
belt-associated ...

Thrilled to share our new paper in @science.org describing our discovery that bacteria can switch from competitors to bonafide predators when resources run dry—arming nanoscale “spears” (T6SS) to stab & consume neighbours.

Antagonism as a foraging strategy in microbial communities
In natural habitats, nutrient availability limits bacterial growth. We discovered that bacteria can overcome this limitation by acquiring nutrients by lysing neighboring cells through contact-dependen...
