ECP
(E. coli common pilus) |
 |
ECP, composed of a 21-kDa pilin subunit EspA, is a pilus-adherence factor that is crucial to the virulence of E. coli O157 in humans, and is also carried by commensal strains of E. coli. It is suggested that pathogenic E. coli strains may use ECP to mimic commensal E. coli and provide themselves with an ecological advantage for host colonization and evasion of the immune system. ... |

A nonhemagglutinating adherence factor and is expressed by approximately 14% of the E. coli known to cause urinary tract infections and 7% of E. coli fecal isolates. Genetically homologous to S fimbriae, but differ in their receptor specificity. ... |

Mannose-resistant (MRHA). Pap pili expression is tightly regulated in response to several environmental and nutritional factors, also controlled by a methylation-dependent phase variation mechanims. The pap operon is a useful example of pilus assembly since it contains many conserved features:. PapD, a conserved chaperone molecule with an Ig-like domain, is necessary to transport several pilus subunits from the cytoplasmic membrane to the outer membrane. PapD-subunit complexes are targeted to the PapC outer membrane usher, which forms a pore through which the the pili are translocated across the OM. The major subunit is PapA, which is assembled into a 6.8-nm thick helical rod that is anchored in the OM by PapH. At the distal end of the pilus rod is a 2-nm linear tip fibrillum composed of a PapE, which is adapted to the PapA rod by PapK. PapG is joined to the PapE tip fibrillum by the adapter protein PapF. ... |
