摘要：

Bacterial pathogens utilize the chaperone-usher pathway to assemble extracellular multi-subunit fibers essential for virulence. The periplasmic chaperone facilitates the initial folding of fiber subunits but then traps them in activated folding transition states. Chaperone dissociation releases the folding energy that drives subunit incorporation into the fiber. which grows through a pore formed by the outermembrane usher. (C) 2004 Elsevier B.V.
