Uncharacterized fimbrial chaperone YcbF

Gene

ycbF

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Part of the elfADCG-ycbUVF fimbrial operon, which promotes adhesion of bacteria to different abiotic surfaces. Could be required for the biogenesis of fimbriae.1 Publication

Miscellaneous

The operon is cryptic under classical laboratory conditions, but is functional when constitutively expressed.1 Publication
