Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology
Your Input:
phoQSensory histidine kinase in two-component regulatory system with PhoP; Member of the two-component regulatory system PhoP/PhoQ involved in adaptation to low Mg(2+) environments and the control of acid resistance genes. In low periplasmic Mg(2+), PhoQ functions as a membrane-associated protein kinase that undergoes autophosphorylation and subsequently transfers the phosphate to PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of PhoP- repressed genes (PRG). In high periplasmic Mg(2+), acts as a protein phosphatase that dephosphorylates phospho-PhoP, resulti [...] (486 aa)
sfmAFimA 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. (180 aa)
sfmCPutative 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)
sfmHFimA 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)
sfmZResponse regulator family protein; Fimbrial Z protein; probable signal transducer; Protein involved in transcription activator activity and transcription. (210 aa)
opgEOPG biosynthetic transmembrane phosphoethanolamine transferase; Catalyzes the addition of a phosphoethanolamine moiety to the osmoregulated periplasmic glucan (OPG) backbone. (527 aa)
csgECurlin secretion specificity factor; May be involved in the biogenesis of curli organelles. (129 aa)
csgACurlin subunit, amyloid curli fibers, cryptic; Curlin is the structural subunit of the curli fimbriae. Curli are coiled surface structures that assemble preferentially at growth temperatures below 37 degrees Celsius. Curli can bind to fibronectin; Belongs to the CsgA/CsgB family. (151 aa)
phoPResponse regulator in two-component regulatory system with PhoQ; Member of the two-component regulatory system PhoP/PhoQ involved in adaptation to low Mg(2+) environments and the control of acid resistance genes. In low periplasmic Mg(2+), PhoQ phosphorylates PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of PhoP-repressed genes (PRG). In high periplasmic Mg(2+), PhoQ dephosphorylates phospho-PhoP, resulting in the repression of PAG and may lead to expression of some PRG (By similarity). Mediates magnesium influx to the cytosol by activation of MgtA. Pro [...] (223 aa)
hlyEHemolysin E; Toxin, which has some hemolytic activity towards mammalian cells. Acts by forming a pore-like structure upon contact with mammalian cells. (303 aa)
parCDNA topoisomerase IV, subunit A; Topoisomerase IV is essential for chromosome segregation; it is the principal protein responsible for decatenating newly replicated chromosomes. It relaxes supercoiled DNA. MukB stimulates the relaxation activity of topoisomerase IV and also has a modest effect on decatenation. Belongs to the type II topoisomerase GyrA/ParC subunit family. ParC type 1 subfamily. (752 aa)
argDBifunctional acetylornithine aminotransferase and succinyldiaminopimelate aminotransferase; Involved in both the arginine and lysine biosynthetic pathways; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. ArgD subfamily. (406 aa)
fimBTyrosine 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)
fimAMajor 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)
fimIFimbrial protein; Protein involved in glycoprotein biosynthetic process. (179 aa)
fimCPeriplasmic chaperone; Required for the biogenesis of type 1 fimbriae. Binds and interact with FimH. (241 aa)
fimHMinor 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. (300 aa)
