  abstract  = {F 1 C fimbriae allow uropathogenic Escherichia coli to adhere to specific epithelial surfaces. This adhesive property is probably due to the presence of minor fimbrial components in F1C fimbriae. The foe gene cluster encoding F1C fimbriae has been cloned, as described previously. Here we present the nucleotide sequence (2081 bp) coding for the F 1 C minor fimbria I subunits. The structural genes code for polypeptides of 175 (FocF), 166 (FocG), and 300 (FocH) amino acids. The deduced amino acids of the F 1 C minor subunits were compared with the reported sequences of the minor subunits of other types of fimbriae. The data show that the Foc minor subunits are highly homologous to the corresponding Sfa proteins, whereas homology to the minor subunits of type 1 and P fimbriae is much lower.},

  abstract  = {The S fimbrial adhesin (sfa) determinant of E. co/i comprises nine genes situated on a stretch of 7.9 kilobases (kb) DNA. Here the nucleotide sequence of the genes sfa B and sfaC situated proximal to the main structural gene sfaA is described. Sfa-LacZ fusions show that the two genes are transcribed in opposite directions. The isolation of mutants in the proximal region of the sfa gene cluster, the construction of sfa-phoA gene fusions and subsequent transcomplementation sturlies indicated that the genes sfaB and sfaC play a role in regulation of the sfa determinant. ln addition the nucleotide sequence of the genes sfa D, sfa E and sfa F situated between the genes sfaA and sfaG responsible for S subunit proteins, were determined. lt is suggested that these genes are involved in transport and assembly of fimbrial subunits. Thus the entire genetic organization of the sfa determinant is presented and compared with the gene clusters coding for P fimbriae (pap), F1 C fimbriae (foc) and type I fimbriae ( fim). The evolutionary relationship of fimbrial adhesin determinants is discussed.},

Sfa and FlC represent functionally distinct 8dbesins in tbeir receptor specificities. Nevertheless, 8 high degree of bomology between both determin8nts was found on the basis of DNA-DNA hybridizations. Characteristic difl'erences in the restriCtion maps of tbe corresponding gene clusters, bowever, were visible in regions coding for the fimbrial subunits and for the S-specific 8dhesin. While a plasmid carrying the geneiic deternlinant for FlC fimbri8e was 8ble to complement transposon-induced sfa mutants, 8 plasmid carrying tbe genetic determin8nt for 8 tbird 8dht\$in type, termed P fimbriae, was un8ble to do so. Proximal sfa-specific sequences carrying the S fimbrial st'"uctural gene were fused to sequences representing tbe di\$tal part of the foc gene cluster to form 8 hybrid cluster, and tbe foc proxim~ region coding for tbe structural protein was Iigated to sfa distal sequences to form 8 second hybrid. Botb hybrid clones produced intact fimbriae.
