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

gltSGlutamate transporter; Catalyzes the sodium-dependent, binding-protein-independent transport of glutamate. Belongs to the glutamate:Na(+) symporter (ESS) (TC 2.A.27) family. (401 aa)    
Predicted Functional Partners:
gltP
Glutamate/aspartate:proton symporter; Catalyzes the proton-dependent, binding-protein-independent transport of glutamate and aspartate. Belongs to the dicarboxylate/amino acid:cation symporter (DAACS) (TC 2.A.23) family. GltP subfamily.
  
  
 0.866
gltF
Periplasmic protein; Involved in induction of the so-called NTR enzymes in response to nitrogen deprivation, as well as in glutamate biosynthesis. May mediate the glutamate-dependent repression of the GLT operon.
      
 0.731
gltI
Glutamate/aspartate periplasmic binding protein; Part of the ABC transporter complex GltIJKL involved in glutamate and aspartate uptake. Binds to both glutamate and aspartate.
      
 0.704
tehA
Potassium-tellurite ethidium and proflavin transporter; Responsible for potassium tellurite resistance when present in high copy number. Ion channel involved in potassium tellurite resistance (By similarity). Otherwise, phenotypically silent. Belongs to the tellurite-resistance/dicarboxylate transporter (TDT) family.
  
    0.658
gadC
Glutamate:gamma-aminobutyric acid antiporter; Involved in glutamate-dependent acid resistance. Imports glutamate inside the cell while simultaneously exporting to the periplasm the GABA produced by GadA and GadB. The gad system helps to maintain a near-neutral intracellular pH when cells are exposed to extremely acidic conditions. The ability to survive transit through the acidic conditions of the stomach is essential for successful colonization of the mammalian host by commensal and pathogenic bacteria; Belongs to the amino acid-polyamine-organocation (APC) superfamily. Glutamate:GABA [...]
      
 0.624
putP
Proline:sodium symporter; Catalyzes the sodium-dependent uptake of extracellular L- proline. This protein is also capable of using lithium as the transport cation. Also catalyzes the uptake of propionate.
      
 0.593
ydjA
Putative oxidoreductase; Belongs to the nitroreductase family.
 
   
 0.564
xanP
Xanthine permease; Specific, proton motive force-dependent high-affinity transporter for xanthine; Belongs to the xanthine/uracil permease family. Nucleobase:cation symporter-2 (NCS2) (TC 2.A.40) subfamily.
  
  
 0.553
nhaA
Sodium-proton antiporter; Na(+)/H(+) antiporter that extrudes sodium in exchange for external protons. Catalyzes the exchange of 2 H(+) per Na(+). Can mediate sodium uptake when a transmembrane pH gradient is applied. Active at alkaline pH. Activity is strongly down-regulated below pH 6.5; Belongs to the NhaA Na(+)/H(+) (TC 2.A.33) antiporter family.
     
 0.538
gltK
Glutamate/aspartate ABC transporter permease; Part of the ABC transporter complex GltIJKL involved in glutamate and aspartate uptake. Probably responsible for the translocation of the substrate across the membrane.
