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

btuBVitamin B12 receptor precursor protein BtuB; 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. (619 aa)    
Predicted Functional Partners:
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.
 
 
 
 0.843
murI
Glutamate racemase; Provides the (R)-glutamate required for cell wall biosynthesis.
  
  
 0.822
ompA
Outer membrane protein A precursor (Outer membrane protein II*); Belongs to the outer membrane OOP (TC 1.B.6) superfamily.
  
  
 0.709
plu1752
Unnamed protein product; Highly similar to outer membrane protein N precursor (Porin OmpN); Belongs to the Gram-negative porin family.
    
 0.702
plu3512
TonB_C domain-containing protein; Unnamed protein product; Some similarities with energy transducer TonB. Putative secreted protein.
 
 
 
 0.684
lamB
Maltoporin precursor (Maltose-inducible porin) (Lambda receptor protein); Involved in the transport of maltose and maltodextrins. Belongs to the porin LamB (TC 1.B.3) family.
  
  
 0.681
plu1030
AAA_31 domain-containing protein; Unnamed protein product; Similar to chromosome partitioning related protein SOJ-like protein.
    
 
 0.641
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.
   
 
 0.633
plu1423
Unnamed protein product; Similar to unknown protein YbfA of Escherichia coli.
  
     0.551
plu3745
Unnamed protein product; Similar to putative polysaccharide export protein YccZ precursor.
     
 0.543
