X-RAY STRUCTURE OF THE CHAPERONE PAPD IN COMPLEX WITH THE PILUS TERMINATOR SUBUNIT PAPH AT 2.3 ANGSTROM RESOLUTION
OverviewOverview
P pili are important adhesive fibres that are assembled by the conserved, chaperone-usher pathway. During pilus assembly, the subunits are, incorporated into the growing fibre by the donor-strand exchange, mechanism, whereby the beta-strand of the chaperone, which complements the, incomplete immunoglobulin fold of each subunit, is displaced by the, amino-terminal extension of an incoming subunit in a zip-in-zip-out, exchange process that is initiated at the P5 pocket, an exposed, hydrophobic pocket in the groove of the subunit. In vivo, termination of P, pilus growth requires a specialized subunit, PapH. Here, we show that PapH, is incorporated at the base of the growing pilus, where it is unable to, undergo donor-strand exchange. This inability is not due to a stronger, PapD-PapH ...
