Bacterial physiology: Type IV pili function as mechanosensors
Christina Tobin K?hrstr?m.
Bacteria use a range of sensory systems to mount appropriate responses to their environment. A new study now shows that the opportunistic pathogen Pseudomonas aeruginosa uses its type IV pili (which are composed of pilin subunits and are mainly used for surface motility) to
