- Tbe genetic organization of tbe foc gene duster bas been studied; six genes involved in tbe biogenesis of Fl C fimbriae were identifi.ed.focA encodes tbe major fimbrial subunit, focC encodes a product tbat is indispensable for fimbria formation,focG andjocH encode minor ftmbrial subunits, andfocl encodes a protein wbicb sbows similarities to the subunit protein FocA. Apart from tbe FocA major subunits, purified FlC fimbriae contain at least two minor subunits, FocG and FocH. Minor proteins of similar size were observed in purified S fimbriae.Tbe genetic organization of tbe foc gene duster bas been studied; six genes involved in tbe biogenesis of Fl C fimbriae were identifi.ed.focA encodes tbe major fimbrial subunit, focC encodes a product tbat is indispensable for fimbria formation,focG andjocH encode minor ftmbrial subunits, andfocl encodes a protein wbicb sbows similarities to the subunit protein FocA.

Remarkably, some mutations in tbe foc gene duster result in an altered 6mbrial morpbology, i.e., rigid stubs or long, curly ftmbriae.…
