Function

[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. [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.

Evolutionary Conservation

Publication Abstract from PubMed

Pilicides block pili formation by binding to pilus chaperones and blocking their function in the chaperone/usher pathway in E. coli. Various C-2 substituents were introduced on the pilicide scaffold by design and synthetic method developments. Experimental evaluation showed that proper substitution of this position affected the biological activity of the compound. Aryl substituents resulted in pilicides with significantly increased potencies as measured in pili-dependent biofilm and hemagglutination assays. The structural basis of the PapD chaperone-pilicide interactions was determined by X-ray crystallography.
