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.

dnaKChaperone and heat shock protein 70 (dnaK); Acts as a chaperone; Belongs to the heat shock protein 70 family. (620 aa)    
Predicted Functional Partners:
grpE
Co-chaperone and heat shock 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. Sev [...]

dnaJ
Co-chaperone and heat shock 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 interact [...]

groL
Chaperone and heat shock protein (groEL); Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.

HP_1024
Co-chaperone-curved DNA binding protein A (CbpA); Similar to GB:L42023 SP:P43735 PID:1007148 PID:1221366 PID:1205479 percent identity: 37.68; identified by sequence similarity; putative.

htpG
Chaperone and heat shock protein C62.5 (htpG); Molecular chaperone. Has ATPase activity.
   
 0.993
groS
Co-chaperone (groES); Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter; Belongs to the GroES chaperonin family.
  
 
 0.987
clpB
ATP-dependent protease binding subunit (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. Acts before DnaK, in the processing of protein aggregates. Protein binding stimulates the ATPase activity; ATP hydrolysis unfolds the denatured protein aggregates, which probably helps expose new hydrophobic binding sites on the surface of ClpB-bound aggregates, contributing to the solubilization and refolding of denatured protein aggregates by DnaK (By similarity). Necessary for sur [...]

HP_0221
nifU-like protein; May be involved in the formation or repair of [Fe-S] clusters present in iron-sulfur proteins.

HP_0033
ATP-dependent C1p protease (clpA); Similar to GB:M31045 SP:P15716 PID:145549 PID:499142 GB:U00096 percent identity: 40.46; identified by sequence similarity; putative; Belongs to the ClpA/ClpB family.

hrcA
Predicted coding region HP0111; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons.
