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

tonB
TonB protein; Interacts with outer membrane receptor proteins that carry out high-affinity binding and energy dependent uptake into the periplasmic space of specific substrates. It could act to transduce energy from the cytoplasmic membrane to specific energy-requiring processes in the outer membrane, resulting in the release into the periplasm of ligands bound by these outer membrane proteins. Belongs to the TonB family.
 
 
 0.969
tolQ
TolQ protein; Part of the Tol-Pal system, which plays a role in outer membrane invagination during cell division and is important for maintaining outer membrane integrity. Required, with TolR, for the proton motive force-dependent activation of TolA and for TolA-Pal interaction.
 
 
 0.949
plu2717
TonB_C domain-containing protein; Unnamed protein product; Similar to unknown protein CjrB of Escherichia coli O164 and some similarities with inner-membrane protein TonB.
 
 
 0.819
plu3512
TonB_C domain-containing protein; Unnamed protein product; Some similarities with energy transducer TonB. Putative secreted protein.
 
 
 0.788
fhuF
Ferric iron reductase protein FhuF.
   
  
 0.678
tolB
TolB protein precursor; Part of the Tol-Pal system, which plays a role in outer membrane invagination during cell division and is important for maintaining outer membrane integrity. TolB occupies a key intermediary position in the Tol-Pal system because it communicates directly with both membrane-embedded components, Pal in the outer membrane and TolA in the inner membrane.
 
  
 0.652
rpoD
RNA polymerase sigma factor rpoD (Sigma-70); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth.
  
   
 0.631
hmuR
Hemin receptor precursor.
  
  
 0.610
secB
Protein-export protein SecB; One of the proteins required for the normal export of preproteins out of the cell cytoplasm. It is a molecular chaperone that binds to a subset of precursor proteins, maintaining them in a translocation-competent state. It also specifically binds to its receptor SecA.
