PubMed Abstract:
Enterotoxigenic Escherichia coli expressing F4 fimbriae are the major cause of porcine colibacillosis and are responsible for significant death and morbidity in neonatal and postweaned piglets. Via the chaperone-usher pathway, F4 fimbriae are assembled into thin, flexible polymers mainly composed of the single-domain adhesin FaeG. The F4 fimbrial system has been labeled eccentric because the F4 pilins show some features distinct from the features of pilins of other chaperone-usher-assembled structures. In particular, FaeG is much larger than other pilins (27 versus approximately 17 kDa), grafting an additional carbohydrate binding domain on the common immunoglobulin-like core. Structural data of FaeG during different stages of the F4 fimbrial biogenesis process, combined with differential scanning calorimetry measurements, confirm the general principles of the donor strand complementation/exchange mechanisms taking place during pilus biogenesis via the chaperone-usher pathway.
