title: Priming virulence factors for delivery into the host.
abstract: Several medically important Gram-negative bacterial pathogens inject virulence factors into host cells through a type III secretion system and specialized bacterial chaperones are required for their effective delivery. Recent structural work shows that these chaperones maintain virulence factors in a partially non-globular conformation that is primed for unfolding and translocation through the 'injectisome'.
