[[https://www.uniprot.org/uniprot/PAPC_ECOLX PAPC_ECOLX]] Involved in the export and assembly of pili subunits across the outer membrane. Forms a hexameric ring-shaped pore in the outer bacterial membrane. The 2 nanometer-diameter pore allows the passage of the thin tip fibrillum. As for the rod, it probably unwinds into linear fibers which would therefore be narrow enough to pass through the pore.

== Publication Abstract from PubMed ==

P pili are extracellular appendages responsible for the targeting of uropathogenic Escherichia coli to the kidney. They are assembled by the chaperone-usher (CU) pathway of pilus biogenesis involving two proteins, the periplasmic chaperone PapD and the outer membrane assembly platform, PapC. Many aspects of the structural biology of the Pap CU pathway have been elucidated, except for the C-terminal domain of the PapC usher, the structure of which is unknown. In this report, we identify a stable and folded fragment of the C-terminal region of the PapC usher and determine its structure using both X-ray crystallography and nuclear magnetic resonance (NMR) spectroscopy. These structures reveal a beta-sandwich fold very similar to that of the plug domain, a domain of PapC obstructing its translocation domain. This structural similarity suggests similar functions in usher-mediated pilus biogenesis, playing out at different stages of the process. This structure paves the way for further functional analysis targeting surfaces common to both the plug and the C-terminal domain of PapC.
