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

lonATP-dependent protease La; ATP-dependent serine protease that mediates the selective degradation of mutant and abnormal proteins as well as certain short- lived regulatory proteins. Required for cellular homeostasis and for survival from DNA damage and developmental changes induced by stress. Degrades polypeptides processively to yield small peptide fragments that are 5 to 10 amino acids long. Binds to DNA in a double-stranded, site-specific manner. (791 aa)    
Predicted Functional Partners:
groEL
60 kD chaperonin (cpn60); Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
   
 
 0.839
hslU
ATP-dependent Hsl protease ATP-binding subunit; ATPase subunit of a proteasome-like degradation complex; this subunit has chaperone activity. The binding of ATP and its subsequent hydrolysis by HslU are essential for unfolding of protein substrates subsequently hydrolyzed by HslV. HslU recognizes the N-terminal part of its protein substrates and unfolds these before they are guided to HslV for hydrolysis.
  
  
 0.825
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.

grpE
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. Several rounds of ATP- [...]

htrA
Serine protease (protease DO); Original (2000) note: Cj1228c, htrA, probable serine protease (protease DO), len: 472 aa; 99.2% identical to TR:Q46120 (EMBL:X82628) C. jejuni serine protease htrA (472 aa), and similar to e.g. HTRA_ECOLI protease DO precursor (EC 3.4.21.-) (474 aa), fasta scores; opt: 965 z-score: 1004.5 E(): 0, 39.5% identity in 461 aa overlap. 50.5% identity to HP1019. Contains Pfam match to entry PF00089 trypsin, and 2x Pfam match to entry PF00595 PDZ, PDZ domain; Updated (2006) note: Characterised in Escherichia coli and Campylobacter jejuni, so putative not added to [...]

dnaJ
Chaperone 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 interactions between DnaJ, DnaK and [...]

dnaK
Heat shock protein DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family.
 
  
 0.793
bamD
Putative lipoprotein; Part of the outer membrane protein assembly complex, which is involved in assembly and insertion of beta-barrel proteins into the outer membrane.
  
    0.770
hslV
ATP-dependent protease HslV; Protease subunit of a proteasome-like degradation complex believed to be a general protein degrading machinery.
   
  
 0.758
clpX
ATP-dependent Clp protease ATP-binding subunit; ATP-dependent specificity component of the Clp protease. It directs the protease to specific substrates. Can perform chaperone functions in the absence of ClpP.
