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. (352 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. [...]
  
  
 0.989
dnaK
Molecular chaperone; Acts as a chaperone; Belongs to the heat shock protein 70 family.
  
  
 0.989
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 [...]

groL
Chaperonin GroEL (HSP60 family); Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
  
  
 0.861
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.
  
  
 0.807
groS
Co-chaperonin GroES (HSP10); Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.
  
  
 0.778
LGAS_0283
ATP-binding subunit of Clp protease and DnaK/DnaJ chaperones; Belongs to the ClpA/ClpB family.
 
  
 0.676
LGAS_1809
ATP-binding subunit of Clp protease and DnaK/DnaJ chaperones; Belongs to the ClpA/ClpB family.
 
  
 0.674
LGAS_1363
ATP-binding subunit of Clp protease and DnaK/DnaJ chaperones; Belongs to the ClpA/ClpB family.
 
  
 0.671
lexA
Transcriptional regulator, xre family; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair.
