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

ompCOuter membrane protein 1b (Ib;c); Forms pores that allow passive diffusion of small molecules across the outer membrane. (367 aa)    
Predicted Functional Partners:
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.

htrA
Periplasmic serine protease Do; DegP acts as a chaperone at low temperatures but switches to a peptidase (heat shock protein) at higher temperatures. It degrades transiently denatured and unfolded proteins which accumulate in the periplasm following heat shock or other stress conditions. DegP is efficient with Val-Xaa and Ile-Xaa peptide bonds, suggesting a preference for beta-branched side chain amino acids. Only unfolded proteins devoid of disulfide bonds appear capable of being cleaved, thereby preventing non-specific proteolysis of folded proteins. Its proteolytic activity is essen [...]

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.
  
  
0.979
ompX
Outer membrane protein X; Residues 1 to 171 of 171 are 100.00 pct identical to residues 1 to 171 of 171 from Escherichia coli K-12 Strain MG1655: B0814.
  
 
 0.953
vacJ
Lipoprotein precursor; Residues 1 to 251 of 251 are 99.60 pct identical to residues 1 to 251 of 251 from Escherichia coli K-12 Strain MG1655: B2346.
   
 
 0.952
lamB
Phage lambda receptor protein; Involved in the transport of maltose and maltodextrins, indispensable for translocation of dextrins containing more than three glucosyl moieties. A hydrophobic path ('greasy slide') of aromatic residues serves to guide and select the sugars for transport through the channel (By similarity); Belongs to the porin LamB (TC 1.B.3) family.
     
 0.946
tsx
Nucleoside channel; Functions as substrate-specific channel for nucleosides and deoxynucleosides; Belongs to the nucleoside-specific channel-forming outer membrane porin (Tsx) (TC 1.B.10) family.
  
 
 0.901
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.
  
 
0.893
tolB
Periplasmic 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.
  
 
 
 0.888
tolC
Outer membrane channel; Residues 1 to 495 of 495 are 99.79 pct identical to residues 1 to 495 of 495 from Escherichia coli K-12 Strain MG1655: B3035.
