Lectin domain organization

The most common group of fimbrial adhesins of Escherichia coli occurs at the edge of their fimbriae and have a two-domain organization. The most external N-terminal domain is a lectin, whereas the C-terminal pilin connects to the rest of the fimbrius. In Fig. 5, the lectin domains from E. coli adhesins that have been crystallised in complex with a specific glycan sequence are displayed, with the exception of CfaE that was only crystallized in its glycan-free form. PapGII (Pap for pyelonephritis associated pili) is the fimbrial adhesin at the tip of P fimbriae from...
