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

dnaKChaperone protein dnaK/HSP70, putative; Acts as a chaperone; Belongs to the heat shock protein 70 family. (609 aa)    
Predicted Functional Partners:
dnaJ
Chaperone protein dnaJ, putative; 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 betwe [...]

grpE
Molecular chaperone GrpE (HSP-70 cofactor), putative; 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 [...]

groEL
60 kDa chaperonin; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
 
 
 0.991
groS
10 kDa chaperonin; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.
  
 
 0.977
rplP
50S ribosomal protein L16, putative; Binds 23S rRNA and is also seen to make contacts with the A and possibly P site tRNAs; Belongs to the universal ribosomal protein uL16 family.
   
 
 0.975
hrcA
Heat shock transcription repressor HrcA, putative; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons.
  
  
 0.974
nifU
NifU family protein, putative; GC: 48.63%; Codon Adaptation Index (CAI): 0.757.
 
 
 0.962
SSA_1274
Hypothetical protein; GC: 39.32%; Codon Adaptation Index (CAI): 0.804. LipoP prediction: SpI. SignalP prediction: Yes (prob. 1).
  
 0.895
SSA_1334
Hypothetical protein; GC: 31.24%; Codon Adaptation Index (CAI): 0.781. Curator(s): J. Alves.
  
 0.895
clpL
ATP-dependent protease, ATP-binding subunit, putative; GC: 47.36%; Codon Adaptation Index (CAI): 0.799; Protein involved in nucleoside-triphosphatase activity; Belongs to the ClpA/ClpB family.
