Function

function

Part of the sfmACDHF fimbrial operon. Could contribute to adhesion to various surfaces in specific environmental niches. Increases adhesion to eukaryotic T24 bladder epithelial cells in the absence of fim genes.

Miscellaneous

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