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

yqiHPutative periplasmic pilin chaperone; Could be required for the biogenesis of a putative fimbria. Belongs to the periplasmic pilus chaperone family. (249 aa)    
Predicted Functional Partners:
ybgQ
Putative outer membrane protein; Could be involved in the export and assembly of the putative YbgD fimbrial subunit across the outer membrane; Belongs to the fimbrial export usher family.
 
 
 0.844
yraJ
Putative outer membrane protein; Part of the yraHIJK 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 operon. Probably involved in the export and assembly of fimbrial subunits across the outer membrane.
  
   0.844
yehB
Putative outer membrane protein; Part of the yehABCD fimbrial operon. Could contribute to adhesion to various surfaces in specific environmental niches. Probably involved in the export and assembly of fimbrial subunits across the outer membrane.
  
   0.842
elfC
Putative outer membrane fimbrial subunit export usher protein; Part of the elfADCG-ycbUVF fimbrial operon, which promotes adhesion of bacteria to different abiotic surfaces. Could be involved in the export and assembly of the ElfA fimbrial subunits across the outer membrane.
  
   0.841
htrE
Putative outer membrane usher protein; Part of the yadCKLM-htrE-yadVN fimbrial operon. Could contribute to adhesion to various surfaces in specific environmental niches. Probably involved in the export and assembly of fimbrial subunits across the outer membrane.
  
   0.840
yhcD
Putative outer membrane fimbrial subunit usher protein; Involved in the export and assembly of a fimbrial subunit across the outer membrane; Belongs to the fimbrial export usher family.
  
   0.839
sfmD
Putative outer membrane export usher protein; 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. Probably involved in the export and assembly of fimbrial subunits across the outer membrane.
  
   0.838
fimD
Fimbrial usher outer membrane porin protein; Involved in the export and assembly of FimA fimbrial subunits across the outer membrane.
  
   0.838
yqiI
Fimbrial protein; May be involved in a fimbrial system chaperoned by YqiH and exported by YqiG.
 
    0.834
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.
