The chaperone/usher pathway is a conserved bacterial secretion system that assembles adhesive fibers termed pili or fimbriae. The usher catalyzes formation of subunit-subunit interactions to promote polymerization of the pilus fiber and provides the channel for the fiber secretion. The mechanism by which the usher catalyzes pilus assembly is not known. Using single molecule FRET method, we studied the conformational dynamics of usher FimD before and after formation of complexes. Our results suggested that the N terminal domain and C terminal domain together regulate the position of the plug domain.
