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

dnaJChaperone Hsp40, co-chaperone with DnaK; 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 interaction [...] (376 aa)    
Predicted Functional Partners:
dnaK
Chaperone Hsp70, co-chaperone with DnaJ; Function experimentally demonstrated in the studied species; factor.
 0.999
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. Several rounds of ATP-depen [...]
 
 
 0.999
htpG
Molecular chaperone HSP90 family; Molecular chaperone. Has ATPase activity.
  
 0.980
hscA
DnaK-like molecular chaperone specific for IscU; Function experimentally demonstrated in the studied species; factor.
 0.976
clpB
Protein disaggregation chaperone; Function experimentally demonstrated in the studied species; factor.
  
 
 0.968
hscC
Hsp70 family chaperone Hsc62, binds to RpoD and inhibits transcription; Function experimentally demonstrated in the studied species; factor.
 0.967
groL
Cpn60 chaperonin GroEL, large subunit of GroESL; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
 
 0.966
groS
Cpn10 chaperonin GroES, small subunit of GroESL; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.
  
 
 0.959
rpoH
RNA polymerase, sigma 32 (sigma H) factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in regulation of expression of heat shock genes.
 
 
 0.918
ydbK
Putative 2-oxoacid-flavodoxin fused oxidoreductase:conserved protein; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
