[[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/PAPH_ECOLX PAPH_ECOLX]] Fimbriae (also called pili), polar filaments radiating from the surface of the bacterium to a length of 0.5-1.5 micrometers and numbering 100-300 per cell, enable bacteria to colonize the epithelium of specific host organs. PapH seems to anchor the pilus to the bacterial cell. In addition the stoichiometric relationship between PapH and PapA determines the pilus length.
