STRINGSTRING
dnaK protein (Maritimibacter alkaliphilus) - STRING interaction network
"dnaK" - Heat shock protein 70 in Maritimibacter alkaliphilus
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

dnaKHeat shock protein 70 ; Acts as a chaperone (636 aa)    
Predicted Functional Partners:
grpE
HSP-70 cofactor ; 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- depend [...] (199 aa)

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, [...] (382 aa)
  0.999
groL
Protein Cpn60 ; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions (544 aa)
 
  0.999
RB2654_19848
ATP-dependent Clp protease, ATP-binding subunit ClpA (777 aa)
   
 
  0.992
clpB
Chaperone protein ClpB ; 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 (873 aa)
   
 
  0.992
hrcA
Heat-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 (354 aa)
   
   
  0.985
groS
Protein Cpn10 ; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter (86 aa)
 
 
  0.983
gyrA
DNA gyrase subunit A ; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner (917 aa)
 
  0.979
rpoH
RNA polymerase sigma-32 factor (298 aa)
   
 
  0.975
fusA
Elongation factor G ; Catalyzes the GTP-dependent ribosomal translocation step during translation elongation. During this step, the ribosome changes from the pre-translocational (PRE) to the post- translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. Catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome (707 aa)
