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.

tonBTonB; Interacts with outer membrane receptor proteins that carry out high-affinity binding and energy dependent uptake into the periplasmic space of specific substrates such as cobalamin, and various iron compounds (such as iron dicitrate, enterochelin, aerobactin, etc.). In the absence of TonB these receptors bind their substrates but do not carry out active transport. TonB also interacts with some colicins and is involved in the energy-dependent, irreversible steps of bacteriophages phi 80 and T1 infection. It could act to transduce energy from the cytoplasmic membrane to specific en [...] (242 aa)    
Predicted Functional Partners:
exbD
tonB-dependent uptake of B colicins; similar to E. coli uptake of enterochelin; tonB-dependent uptake of B colicins (AAC76041.1); Blastp hit to AAC76041.1 (141 aa), 93% identity in aa 1 - 141.
 
 
 0.999
exbB
Uptake of enterochelin; Involved in the TonB-dependent energy-dependent transport of various receptor-bound substrates. Protects ExbD from proteolytic degradation and functionally stabilizes TonB (By similarity).
  
 
 0.999
fhuA
Iron complex outermembrane recepter protein; Similar to E. coli outer membrane protein receptor for ferrichrome, colicin M, and phages T1, T5, and phi80 (AAC73261.1); Blastp hit to AAC73261.1 (747 aa), 68% identity in aa 1 - 747.
 
 
 0.991
fepA
Similar to E. coli outer membrane receptor for ferric enterobactin (enterochelin) and colicins B and D (AAC73685.1); Blastp hit to AAC73685.1 (746 aa), 81% identity in aa 1 - 746.
 
 
 0.978
phoE
Outer membrane pore protein e (e,ic,nmpab); Uptake of inorganic phosphate, phosphorylated compounds, and some other negatively charged solutes; Belongs to the Gram-negative porin family.
  
   
 0.973
rpoB
RNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
     
 0.963
infB
Protein chain initiation factor IF-2; One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex (By similarity).
     
 0.962
mdh
Malate dehydrogenase; Catalyzes the reversible oxidation of malate to oxaloacetate.
     
 0.958
gapA
Glyceraldehyde-3-phosphate dehydrogenase A; Catalyzes the oxidative phosphorylation of glyceraldehyde 3- phosphate (G3P) to 1,3-bisphosphoglycerate (BPG) using the cofactor NAD. The first reaction step involves the formation of a hemiacetal intermediate between G3P and a cysteine residue, and this hemiacetal intermediate is then oxidized to a thioester, with concomitant reduction of NAD to NADH. The reduced NADH is then exchanged with the second NAD, and the thioester is attacked by a nucleophilic inorganic phosphate to produce BPG.
     
 0.955
tolR
Tol protein, role in outer membrane integrity; 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.
