STRINGSTRING
hrcA protein (Desulfovibrio vulgaris Hildenborough) - STRING interaction network
"hrcA" - Heat-inducible transcription repressor HrcA in Desulfovibrio vulgaris Hildenborough
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

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 (355 aa)    
Predicted Functional Partners:
grpE
Protein GrpE; 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 [...] (191 aa)
   
   
  0.996
dnaK
Chaperone protein DnaK; Acts as a chaperone (636 aa)
   
   
  0.994
groES
10 kDa chaperonin; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter (95 aa)
     
   
  0.866
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, D [...] (376 aa)
   
   
  0.817
groEL
60 kDa chaperonin; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions (547 aa)
   
   
  0.753
birA
Bifunctional ligase/repressor BirA; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a repressor (330 aa)
           
  0.639
clpA
ATP-dependent Clp protease, ATP-binding subunit ClpA; Identified by similarity to SP-P15716; match to protein family HMM PF00004; match to protein family HMM PF02861 (776 aa)
   
   
  0.634
rimM
Ribosome maturation factor RimM; An accessory protein needed during the final step in the assembly of 30S ribosomal subunit, possibly for assembly of the head region. Probably interacts with S19. Essential for efficient processing of 16S rRNA. May be needed both before and after RbfA during the maturation of 16S rRNA. It has affinity for free ribosomal 30S subunits but not for 70S ribosomes; Belongs to the RimM family (176 aa)
           
  0.630
lepA
Elongation factor 4; Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back- translocation proceeds from a post-translocation (POST) complex to a pre-translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP-dependent manner (601 aa)
         
  0.590
ruvB
Holliday junction ATP-dependent DNA helicase RuvB; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing (320 aa)
