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

tolBPeriplasmic protein involved in the tonb-independent uptake of group A colicins; 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. (430 aa)    
Predicted Functional Partners:
pal
Peptidoglycan-associated lipoprotein; 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.
 
 
 0.999
tolR
Putative inner membrane protein, involved in the tonB-independent uptake of group A colicins; 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 TolQ, for the proton motive force-dependent activation of TolA and for TolA-Pal interaction.
  
 0.998
tolQ
Inner membrane protein, membrane-spanning, maintains integrity of cell envelope; 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.
 
  
 0.997
ybgF
Orf, hypothetical protein; Mediates coordination of peptidoglycan synthesis and outer membrane constriction during cell division; Belongs to the CpoB family.
 
  
 0.993
ompF
Outer membrane protein 1a (Ia;b;F); Residues 1 to 362 of 362 are 99.44 pct identical to residues 1 to 362 of 362 from Escherichia coli K-12 Strain MG1655: B0929; Belongs to the Gram-negative porin family.
  
 
 
 0.969
ompA
Outer membrane protein 3a (II*;G;d); With TolR probably plays a role in maintaining the position of the peptidoglycan cell wall in the periplasm. Acts as a porin with low permeability that allows slow penetration of small solutes; an internal gate slows down solute passage.
  
 
 0.958
lpp
Murein lipoprotein; A highly abundant outer membrane lipoprotein that controls the distance between the inner and outer membranes. The only protein known to be covalently linked to the peptidoglycan network (PGN). Also non-covalently binds the PGN. The link between the cell outer membrane and PGN contributes to maintenance of the structural and functional integrity of the cell envelope, and maintains the correct distance between the PGN and the outer membrane.
  
 
 
 0.940
btuB
Outer membrane receptor for transport of vitamin B12, E colicins, and bacteriophage BF23; Involved in the active translocation of vitamin B12 (cyanocobalamin) across the outer membrane to the periplasmic space. It derives its energy for transport by interacting with the trans- periplasmic membrane protein TonB; Belongs to the TonB-dependent receptor family. BtuB (TC 1.B.14.3.1) subfamily.
    
 
 0.901
ompC
Outer membrane protein 1b (Ib;c); Forms pores that allow passive diffusion of small molecules across the outer membrane.
  
 
 
 0.888
phoE
Outer membrane pore protein E (E,Ic,NmpAB); Residues 1 to 351 of 351 are 99.71 pct identical to residues 1 to 351 of 351 from Escherichia coli K-12 Strain MG1655: B0241; Belongs to the Gram-negative porin family.
