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

hrcAHeat-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. (345 aa)    
Predicted Functional Partners:
grpE
Molecular chaperone GrpE (heat 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. [...]
  
  
 0.992
dnaK
Molecular chaperone; Acts as a chaperone; Belongs to the heat shock protein 70 family.
  
  
 0.988
dnaJ
DnaJ-class molecular chaperone with C-terminal Zn finger domain; 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 A [...]
  
  
 0.943
clpB
ATP-binding subunit of Clp protease and DnaK/DnaJ chaperones; 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; Belongs to the ClpA/ClpB family.
 
  
 0.855
groS
Co-chaperonin GroES (HSP10); Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.
  
  
 0.852
groL
Chaperonin GroEL (HSP60 family); Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
  
  
 0.841
clpP
ATP-dependent Clp protease proteolytic subunit ClpP; Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins. Belongs to the peptidase S14 family.
   
  
 0.825
LVIS_1701
Transcriptional repressor of class III stress genes; Belongs to the CtsR family.
   
  
 0.649
LVIS_1554
ATP-binding subunit of Clp protease and DnaK/DnaJ chaperones; Belongs to the ClpA/ClpB family.
 
  
 0.609
LVIS_1332
FMN adenylyltransferase / riboflavin kinase; Belongs to the ribF family.
       0.583
