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

DnaKMolecular chaperone; Acts as a chaperone; Belongs to the heat shock protein 70 family. (606 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. [...]

DnaJ
Molecular chaperones (contain 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 ATP-de [...]

HrcA
Transcriptional regulator of heat shock gene; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons.
  
  
 0.996
GroL
Chaperonin GroEL (HSP60 family); Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
 
 
 0.993
ClpA
ATPases with chaperone activity, ATP-binding subunit; Best Blastp hit = gi|10172715|dbj|BAB03822.1| (AP001507) class III stress response-related ATPase [Bacillus halodurans], score 973, E-value 0; Belongs to the ClpA/ClpB family.
  
 
 0.980
GroS
Co-chaperonin GroES (HSP10); Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.
 
 
 0.975
TTE1799
Hypothetical protein.
  
 0.882
IscU
NifU homologs involved in Fe-S cluster formation; Best Blastp hit = gi|7387932|sp|O32163|NIFU_BACSU NIFU-LIKE PROTEIN gi|7427865|pir||E70019 nitrogen fixation protein nifU homolog yurV - Bacillus subtilis gi|2635764|emb|CAB15257.1| (Z99120) similar to NifU protein homolog [Bacillus subtilis], score 129, E-value 1.00E-29.
  
 
 0.868
ClpP
Protease subunit of ATP-dependent Clp proteases; 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.
   
 
 0.864
GyrB
DNA gyrase (topoisomerase II) B subunit; 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-depen [...]
