 -!- FUNCTION: Fimbriae (also called pili), polar filaments radiating
     from the surface of the bacterium to a length of 0.5-1.5
     micrometers and numbering 100-300 per cell, enable bacteria to
     colonize the epithelium of specific host organs.
 -!- FUNCTION: A minor fimbrial subunit. This protein is necessary for
     full expression of S-specific binding. S-fimbrial adhesins enable
     pathogenic E.coli causing urinary-tract infections or newborn
     meningitis to attach to glycoproteins terminating with alpha-
     sialic acid-(2-3)-beta-Gal.
 -!- SUBCELLULAR LOCATION: Fimbrium {ECO:0000269|PubMed:2576095}.
 -!- DISRUPTION PHENOTYPE: Deletion decreases hemagglutination but no
     decrease in fimbriation levels. {ECO:0000269|PubMed:2576095}.
 -!- SIMILARITY: Belongs to the fimbrial protein family. {ECO:0000305}.
 -!- SEQUENCE CAUTION:
     Sequence=ABG68332.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305};
