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

htrASerine proteinase; HtrA. (356 aa)    
Predicted Functional Partners:
prrIV2
ATP-dependent 26S proteinase regulatory subunit 4 homolog; ATPase which is responsible for recognizing, binding, unfolding and translocation of substrate proteins into the archaeal 20S proteasome core particle. Is essential for opening the gate of the 20S proteasome via an interaction with its C-terminus, thereby allowing substrate entry and access to the site of proteolysis. Thus, the C- termini of the proteasomal ATPase function like a 'key in a lock' to induce gate opening and therefore regulate proteolysis. Unfolding activity requires energy from ATP hydrolysis, whereas ATP binding [...]

dnaK
Heat shock protein; Acts as a chaperone.
  
 
 0.866
glpK
Glycerol kinase; Key enzyme in the regulation of glycerol uptake and metabolism. Catalyzes the phosphorylation of glycerol to yield sn- glycerol 3-phosphate.
   
 0.821
rpl40e
50S ribosomal protein L40E; Rpl40e; Belongs to the eukaryotic ribosomal protein eL40 family.
   
 
  0.793
lon
Lipoate protein ligase; ATP-dependent serine protease that mediates the selective degradation of mutant and abnormal proteins as well as certain short- lived regulatory proteins. Degrades polypeptides processively (By similarity).

VNG_0429H
Hypothetical protein; Vng0429h.
  
  
 0.752
ids
Bifunctional short chain isoprenyl diphosphate synthase; Ids.
  
 
 0.751
dnaJ
Heat shock 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 [...]
 
 
 0.748
cctB
Thermosome subunit beta; Molecular chaperone; binds unfolded polypeptides in vitro, and has a weak ATPase activity; Belongs to the TCP-1 chaperonin family.
