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

clpCEndopeptidase, putative; Required for growth at high temperatures, probably by acting as a chaperone during heat shock and targeting heat-denatured proteins for degradation by ClpP. Required for biofilm formation. May act as a chaperone regulating CtsR activity. (818 aa)    
Predicted Functional Partners:
clpP
ATP-dependent Clp protease, proteolytic subunit ClpP; 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.
  
 
 0.995
mecA
Conserved hypothetical protein; Enables the recognition and targeting of unfolded and aggregated proteins to the ClpC protease or to other proteins involved in proteolysis.
   
 
 0.991
mcsB
ATP:guanido phosphotransferase, C-terminal catalytic domain protein; Catalyzes the specific phosphorylation of arginine residues in proteins (By similarity). Is required for stress tolerance and virulence in S.aureus. Acts as a modulator of the repressor activity of CtsR upon heavy metal and oxidative stress caused by these metal ions.
  
 
 0.984
dnaK
DNAk protein, putative; Acts as a chaperone; Belongs to the heat shock protein 70 family.
  
 
 0.965
ctsR
Conserved hypothetical protein; Negative regulator of clpC, clpB and clpP transcription by binding directly and specifically to their promoter region.
  
  
 0.960
mcsA
UvrB/uvrC motif domain protein; Activates the phosphorylation activity of the protein- arginine kinase McsB (By similarity). May function as an important molecule for oxidative tolerance in various types of stress including that of heavy metals. Binds to Cu(2+), Zn(2+), Co(2+) and Cd(2+) via its CXXC metal binding motifs.
 
  
 0.959
groS
Chaperonin, 10 kDa, GroES, putative; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.
  
 
 0.875
grpE
Co-chaperone 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. Several rounds of ATP-depend [...]
  
 
 0.866
clpX
ATP-dependent Clp protease, ATP-binding subunit ClpX; ATP-dependent specificity component of the Clp protease. It directs the protease to specific substrates. Can perform chaperone functions in the absence of ClpP.
   
 
 0.866
dnaJ
DnaJ protein; 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, DnaK and Gr [...]
