Escherichia coli K-12 substr. MG1655 Polypeptide: predicted fimbrial-like adhesin protein



Gene: yfcP Accession Numbers: G7204 (EcoCyc), b2333, ECK2327

Regulation Summary Diagram: ?

Summary:
yfcOPQRSTUV is a putative chaperone-usher fimbrial operon in E.coli K-12[Korea10]. The operon is cryptic under normal laboratory conditions but when constitutive expression is induced in a strain that lacks the type 1 fimbrial complex the yfc operon promotes adhesion to eukaryotic epithelial cells (T4 bladder cells) [Korea10]. Expression of the yfc operon is regulated by the global regulators H-NS and CRP cAMP [Korea10].
