F17a-G fimbrial adhesin

Gene

f17aG

Organism
Escherichia coli
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Essential fimbrial adhesion factor that mediates binding to N-acetylglucosamine-containing receptors in the host intestinal microvilli, leading to colonization of the intestinal tissue, and diarrhea or septicemia. Also confers adhesiveness to laminin and basement membranes.1 Publication

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
