Disease relevance of ECs5276

  • Adhesive type 1 pili from uropathogenic Escherichia coli are filamentous protein complexes that are attached to the assembly platform FimD in the outer membrane [1].
 

High impact information on ECs5276

  • During pilus assembly, FimD binds complexes between the chaperone FimC and type 1 pilus subunits in the periplasm and mediates subunit translocation to the cell surface [1].
  • Mutagenesis of the P pilus usher PapC and the type 1 pilus usher FimD was undertaken to elucidate the initial stages of pilus biogenesis at the OM [2].
 

Biological context of ECs5276

  • Similarly, an intact FimD N terminus was required for chaperone-subunit binding and pilus biogenesis [2].
