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-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. (347 aa)    
Predicted Functional Partners:
grpE
GrpE 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. Several rounds of ATP-dependent i [...]

dnaJ
Chaperone DnaJ domain 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 [...]

dnaK
Chaperone protein DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family.

ADU48652.1
Protein of unknown function DUF558; Specifically methylates the N3 position of the uracil ring of uridine 1498 (m3U1498) in 16S rRNA. Acts on the fully assembled 30S ribosomal subunit.

ADU49780.1
COGs: COG0484 DnaJ-class molecular chaperone with C-terminal Zn finger domain; InterProIPR018260: IPR018253: IPR001623: IPR003095: IPR 002939; KEGG: kra:Krad_4231 chaperone DnaJ domain protein; PFAM: chaperone DnaJ domain protein; heat shock protein DnaJ domain protein; SMART: heat shock protein DnaJ domain protein; SPTR: DnaJ protein; PFAM: DnaJ C terminal region; DnaJ domain.
  
  
 0.694
ADU48655.1
KEGG: kse:Ksed_11680 hypothetical protein; SPTR: Putative uncharacterized protein; manually curated; PFAM: Protein of unknown function (DUF3097).
       0.643
lexA
SOS-response transcriptional repressor, LexA; 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.
  
   
 0.590
groS
Chaperonin Cpn10; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.
  
  
 0.588
ADU49779.1
Transcriptional regulator, MerR family; COGs: COG0789 transcriptional regulator protein; InterPro IPR000551; KEGG: kra:Krad_4230 putative transcriptional regulator, MerR family; PFAM: regulatory protein MerR; SMART: regulatory protein MerR; SPTR: Putative transcriptional regulator; PFAM: MerR family regulatory protein.
   
 
 0.572
recA
recA protein; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage; Belongs to the RecA family.
