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 GrpE; 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- [...] (200 aa)    
Predicted Functional Partners:
dnaK
dnaK protein; Acts as a chaperone; Belongs to the heat shock protein 70 family.
 
 0.997
dnaJ
dnaJ protein; 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, DnaK and Gr [...]

groL1
Chaperonin, 60 Kd subunit; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
 
 0.968
hscA
Chaperone protein HscA; Probable chaperone. Has a low intrinsic ATPase activity which is markedly stimulated by HscB (By similarity).
 
 0.966
groL2
Chaperonin, 60 Kd subunit; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
 
 0.964
VC_1386
Heat shock protein 70 family protein; Similar to SP:P36928 GB:U00096 PID:1788384; identified by sequence similarity; putative.
  
 0.958
VC_1373
DnaK-related protein; Similar to SP:O32482; identified by sequence similarity; putative.
  
 0.955
VC_1374
DnaK-related protein; Similar to SP:O32482; identified by sequence similarity; putative; Belongs to the heat shock protein 70 family.
  
 0.955
VC_A0788
DnaJ-related protein; Similar to SP:P48207 PID:893246; identified by sequence similarity; putative.
  
 
 0.946
hslU
Protease HslVU, ATPase 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.
