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

hrcAhrcA: heat-inducible transcription repressor HrcA; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons. (347 aa)    
Predicted Functional Partners:
dnaK
Chaperone protein DnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family.
  
  
 0.934
grpE
Molecular chaperone GrpE (heat shock protein); 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. [...]

dnaJ-2
Chaperone 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 interactions between DnaJ, D [...]

AHY46803.1
TIGR00046: RNA methyltransferase, RsmE family; Specifically methylates the N3 position of the uracil ring of uridine 1498 (m3U1498) in 16S rRNA. Acts on the fully assembled 30S ribosomal subunit.
  
  
 0.832
groL
GroEL: chaperonin GroL; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
  
  
 0.764
clpP
Protease subunit of ATP-dependent Clp protease; 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.
   
  
 0.741
lepA
lepA: GTP-binding protein LepA; Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre- translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP- dependent manner.

AHY46802.1
Hypothetical protein; COG:COG1610: Uncharacterized conserved protein [Function unknown]; Pfam:PF09424:Uncharacterised domain YOR215C, mitochondrial; Pfam:PF09424:Uncharacterised domain YOR215C, mitochondrial; SUPERFAMILY:SSF89095:Aspartyl/glutamyl-tRNA amidotransferase subunit B-related.
       0.658
AHY46801.1
COG:COG1702: Phosphate starvation-inducible protein PhoH predicted ATPase [Signal transduction mechanisms]; Pfam:PF02562:PhoH-like protein; Pfam:PF02562:PhoH-like protein; SMART:SM00322:K Homology domain; SUPERFAMILY:SSF52540:P-loop containing nucleoside triphosphate hydrolase.
       0.639
groS
Co-chaperonin GroES (HSP10); Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter.
