- | [[http://www.uniprot.org/uniprot/PAPD_ECOLX PAPD_ECOLX]] Binds and caps interactive surfaces on pilus subunits to prevent them from participating in non-productive interactions. Facilitates the import of subunits into the periplasm. May facilitate subunit folding. Chaperone-subunit complexes are then targeted to the PapC outer membrane usher where the chaperone must uncap from the subunits. [[http://www.uniprot.org/uniprot/PAPE_ECOLX PAPE_ECOLX]] Repeated PapE subunits make up the thin (2 nm in diameter) tip fibrillum of the pilus. Subunits are arranged in a open helical conformation. Pili with a defective papE gene have low adhesive capacity or none; however, the binding property of the whole cell is not affected. Pili are polar filaments radiating from the surface of the bacterium to a length of 0.5-1.5 micrometers and numbering 100-300 per cell, and enable bacteria to colonize the epithelium of specific host organs. | ||
