atpD | F1 sector of membrane-bound ATP synthase, beta subunit; Produces ATP from ADP in the presence of a proton gradient across the membrane. The catalytic sites are hosted primarily by the beta subunits. (460 aa) | ||||
acrA | Multidrug efflux system; AcrA-AcrB-AcrZ-TolC is a drug efflux protein complex with broad substrate specificity that uses the proton motive force to export substrates. This subunit may act as an adapter protein that links AcrB and TolC stably together. It is elongated in shape, being long enough to span the periplasm. (397 aa) | ||||
sfmC | Putative periplasmic pilus chaperone; 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. (230 aa) | ||||
sfmH | FimA homolog, function unknown; 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. (327 aa) | ||||
fes | Enterobactin/ferrienterobactin esterase; Upon internalization, ferric enterobactin is processed via an exquisitely specific pathway that is dependent on FES activity, making iron available for metabolic use; Belongs to the Fes family. (400 aa) | ||||
lrp | Leucine-responsive global transcriptional regulator; Mediates a global response to leucine. Exogenous leucine affects the expression of a number of different operons; lrp mediates this effect for at least some of these operons. For example it is regulator of the branched-chain amino acid transport genes. (164 aa) | ||||
flgM | Anti-sigma factor for FliA (sigma 28); Responsible for the coupling of flagellin expression to flagellar assembly by preventing expression of the flagellin genes when a component of the middle class of proteins is defective. It negatively regulates flagellar genes by inhibiting the activity of FliA by directly binding to FliA; Belongs to the FlgM family. (97 aa) | ||||
fliA | RNA polymerase, sigma 28 (sigma F) factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor controls the expression of flagella-related genes. (239 aa) | ||||
fliC | Flagellar filament structural protein (flagellin); Flagellin is the subunit protein which polymerizes to form the filaments of bacterial flagella. (498 aa) | ||||
fliF | Flagellar basal-body MS-ring and collar protein; The M ring may be actively involved in energy transduction; Belongs to the FliF family. (552 aa) | ||||
gyrA | DNA gyrase (type II topoisomerase), subunit A; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to maintain chromosomes in an underwound state. This makes better substrates for topoisomerase IV (ParC and ParE) which is the main enzyme that unlinks newly replicated chromosomes in E.coli. Gyrase catalyzes the interconversion of other topological isomers of dsDNA rings, including catenanes. Relaxes negatively supercoiled DNA in an ATP-independent manner. E.coli gyrase has higher supercoiling activity than many other bac [...] (875 aa) | ||||
yfaL | Adhesin; Probably an autotransporter. (1250 aa) | ||||
rpmJ | 50S ribosomal subunit protein L36; Protein involved in structural constituent of ribosome and translation; Belongs to the bacterial ribosomal protein bL36 family. (38 aa) | ||||
crp | cAMP-activated global transcription factor, mediator of catabolite repression; A global transcription regulator. Complexes with cyclic AMP (cAMP) which allosterically activates DNA binding (to consensus sequence 5'-AAATGTGATCTAGATCACATTT-3') to directly regulate the transcription of about 300 genes in about 200 operons and indirectly regulate the expression of about half the genome. There are 3 classes of CRP promoters; class I promoters have a single CRP-binding site upstream of the RNA polymerase (RNAP)-binding site, whereas in class II promoters the single CRP- and RNAP-binding site [...] (210 aa) | ||||
atpC | F1 sector of membrane-bound ATP synthase, epsilon subunit; Produces ATP from ADP in the presence of a proton gradient across the membrane; Belongs to the ATPase epsilon chain family. (139 aa) | ||||
atpB | F0 sector of membrane-bound ATP synthase, subunit a; Key component of the proton channel; it plays a direct role in the translocation of protons across the membrane. (271 aa) | ||||
rpmE | 50S ribosomal subunit protein L31; Binds the 23S rRNA. (70 aa) | ||||
fimB | Tyrosine recombinase/inversion of on/off regulator of fimA; FimB is one of the 2 regulatory proteins which control the phase variation of type 1 fimbriae in E.coli. These proteins mediate the periodic inversion of a 300bp DNA segment that harbors the promoter for the fimbrial structural gene, FimA. FimB switches FimA on. (200 aa) | ||||
fimE | Tyrosine recombinase/inversion of on/off regulator of fimA; FimE is one of the 2 regulatory proteins which control the phase variation of type 1 fimbriae in E.coli. These proteins mediate the periodic inversion of a 300bp DNA segment that harbors the promoter for the fimbrial structural gene, fimA. FimE switches fimA off. (198 aa) | ||||
fimA | Major type 1 subunit fimbrin (pilin); Fimbriae (also called pili), polar filaments radiating from the surface of the bacterium to a length of 0.5-1.5 micrometers and numbering 100-300 per cell, enable bacteria to colonize the epithelium of specific host organs. (182 aa) | ||||
fimI | Fimbrial protein; Protein involved in glycoprotein biosynthetic process. (179 aa) | ||||

fimH | Minor component of type 1 fimbriae; Involved in regulation of length and mediation of adhesion of type 1 fimbriae (but not necessary for the production of fimbriae). Adhesin responsible for the binding to D-mannose. It is laterally positioned at intervals in the structure of the type 1 fimbriae. In order to integrate FimH in the fimbriae FimF and FimG are needed.
