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.

hrcAHeat shock transcription repressor HrcA, putative; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons. (344 aa)    
Predicted Functional Partners:
grpE
Molecular chaperone GrpE (HSP-70 cofactor), putative; 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 [...]
  
  
 0.994
dnaK
Chaperone protein dnaK/HSP70, putative; Acts as a chaperone; Belongs to the heat shock protein 70 family.
  
  
 0.977
dnaJ
Chaperone protein dnaJ, putative; 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 betwe [...]
  
  
 0.901
groEL
60 kDa chaperonin; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
  
  
 0.824
groS
10 kDa chaperonin; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.
  
  
 0.748
ctsR
Firmicutes transcriptional repressor of class III stress genes (CtsR), putative; GC: 44.73%; Codon Adaptation Index (CAI): 0.768. Curator(s): J. Alves; Protein involved in response to unfolded protein; Belongs to the CtsR family.
   
  
 0.695
SSA_2012
Conserved hypothetical protein; GC: 39.79%; Transmembrane domains: 2. Codon Adaptation Index (CAI): 0.781. Curator(s): T. Kitten, J. Alves.
       0.653
birA
Biotin--[acetyl-CoA-carboxylase] ligase, putative; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a repressor; Belongs to the biotin--protein ligase family.
   
  
 0.642
SSA_2013
Conserved hypothetical protein; GC: 41.98%; Codon Adaptation Index (CAI): 0.779.
       0.610
htpX
HtpX protease, putative; GC: 48.05%; Transmembrane domains: 4. Codon Adaptation Index (CAI): 0.784. SignalP prediction: Yes (prob. 0.893); Curator(s): D. Akan; Protein involved in hydrolase activity and metal ion binding; Belongs to the peptidase M48B family.
