STRINGSTRING
hrcA protein (Alcaligenes faecalis) - STRING interaction network
"hrcA" - Heat-inducible transcription repressor HrcA in Alcaligenes faecalis
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

hrcAHeat-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 (337 aa)    
Predicted Functional Partners:
grpE
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- dependent [...] (196 aa)
   
   
  0.997
dnaK
Chaperone protein DnaK; Acts as a chaperone (641 aa)
   
   
  0.995
JT27_14715
DNA repair protein RecN; May be involved in recombinational repair of damaged DNA (549 aa)
         
  0.773
hemH
Ferrochelatase; Catalyzes the ferrous insertion into protoporphyrin IX; Belongs to the ferrochelatase family (361 aa)
              0.772
ppnK
NAD kinase; Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2’-hydroxyl of the adenosine moiety of NAD to yield NADP (299 aa)
              0.733
dnaJ
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 [...] (377 aa)
   
   
  0.703
groEL
60 kDa chaperonin; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions (548 aa)
   
   
  0.697
groS
10 kDa chaperonin; Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter (95 aa)
     
   
  0.674
lepA
Elongation factor 4; 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 (597 aa)
         
  0.631
guaB
Inosine-5’-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5’-phosphate (IMP) to xanthosine 5’-phosphate (XMP), the first committed and rate- limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth; Belongs to the IMPDH/GMPR family (486 aa)
