STRINGSTRING
STRING protein interaction network
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

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)    
Predicted Functional Partners:
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.
  
  
 0.952
sfmA
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.
      
 0.940
yeiR
Zn-stimulated GTPase involved in zinc homeostasis; Involved in metal homeostasis. Has GTPase activity. Binds several Zn(2+) ions in vitro.
   
  
 0.893
fimC
Periplasmic chaperone; Required for the biogenesis of type 1 fimbriae. Binds and interact with FimH.
   
  
 0.892
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.
      
 0.877
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.
      
 0.860
fimI
Fimbrial protein; Protein involved in glycoprotein biosynthetic process.
   
  
 0.822
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.
      
 0.817
fimF
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). Involved in the integration of FimH in the fimbriae; Belongs to the fimbrial protein family.
   
  
 0.791
fruK
Fructose-1-phosphate kinase; Protein involved in glycolysis; Belongs to the carbohydrate kinase PfkB family.
   
  
 0.790
