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

grpEHeat shock protein; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins, in association with DnaK and GrpE. It is the nucleotide exchange factor for DnaK and may function as a thermosensor. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-depen [...] (194 aa)    
Predicted Functional Partners:
dnaK
Chaperone protein dnaK (Heat shock 70 kDa protein); Acts as a chaperone; Belongs to the heat shock protein 70 family.
 
 0.980
dnaJ
Chaperone protein DnaJ; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-dependent interactions between DnaJ, D [...]

groL
60 kDa chaperonin (Protein Cpn60); Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
 
 0.963
groS
10 kDa chaperonin (Protein Cpn10); Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.
 
 
 0.940
yegD
Putative heat shock protein YegD; silverDB:etchr01304.
  
 0.919
hslU
ATP-dependent hsl protease ATP-binding subunit HslU; ATPase subunit of a proteasome-like degradation complex; this subunit has chaperone activity. The binding of ATP and its subsequent hydrolysis by HslU are essential for unfolding of protein substrates subsequently hydrolyzed by HslV. HslU recognizes the N-terminal part of its protein substrates and unfolds these before they are guided to HslV for hydrolysis.
   
  
 0.901
ppnK
Probable inorganic polyphosphate/ATP-NAD kinase; Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP.
 
     0.855
hslV
ATP-dependent protease HslV; Protease subunit of a proteasome-like degradation complex believed to be a general protein degrading machinery.
   
  
 0.849
htpG
Heat shock protein (High temperature protein G); Molecular chaperone. Has ATPase activity.
   
 
 0.820
ETA_09880
Lambdoid prophage Qin antitermination protein Q-like protein; silverDB:etchr00979.
  
 
 0.809
