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.

spr1999Class III stress response-related ATPase, truncation. (47 aa)    
Predicted Functional Partners:
ctsR
Transcriptional regulator CtsR; Belongs to the CtsR family.
  
  
 0.884
dnaK
Class I heat-shock protein (molecular chaperone); Acts as a chaperone; Belongs to the heat shock protein 70 family.
  
 
 0.803
spr2000
Class III stress response-related ATPase, truncation; Belongs to the ClpA/ClpB family.
       0.773
clpP
ATP-dependent CLP protease proteolytic subunit; 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.
  
 
 0.749
mecA
Negative regulator of genetic competence; Enables the recognition and targeting of unfolded and aggregated proteins to the ClpC protease or to other proteins involved in proteolysis.
  
 
 0.683
dnaJ
Heat-shock protein (activation of 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 [...]

spr2003
Conserved hypothetical protein.
       0.608
ABC-NBD-30
ABC transporter ATP-binding protein - anion transport.
       0.605
grpE
Heat-shock protein (activation of DnaK); 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. Severa [...]

ABC-MSP-21
ABC transporter membrane-spanning permease - unknown substrate.
