STRINGSTRING
grpE protein (Methylobacter tundripaludum) - STRING interaction network
"grpE" - HSP-70 cofactor in Methylobacter tundripaludum
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

grpEHSP-70 cofactor ; 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- depend [...] (203 aa)    
Predicted Functional Partners:
dnaK
Heat shock protein 70 ; Acts as a chaperone (644 aa)
 
  0.999
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, [...] (376 aa)

clpB
Chaperone protein ClpB ; Part of a stress-induced multi-chaperone system, it is involved in the recovery of the cell from heat-induced damage, in cooperation with DnaK, DnaJ and GrpE (858 aa)
   
 
  0.993
Mettu_3601
Heat shock protein 70 (432 aa)
 
  0.993
groL
Protein Cpn60 ; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions (550 aa)
 
  0.990
Mettu_3235
DnaK-related protein (646 aa)
   
  0.988
Mettu_0186
Putative chaperone heat-shock protein (932 aa)
   
  0.988
groS
Protein Cpn10 ; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter (95 aa)
     
 
  0.982
hrcA
Heat-inducible transcription repressor HrcA ; Negative regulator of class I heat shock genes (grpE- dnaK-dnaJ and groELS operons). Prevents heat-shock induction of these operons (372 aa)
   
   
  0.981
rpoH
RNA polymerase sigma-32 factor ; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in regulation of expression of heat shock genes (285 aa)
