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

hrcAProbable heat shock protein transcriptional repressor HrcA; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons; Belongs to the HrcA family. (343 aa)    
Predicted Functional Partners:
dnaJ2
Probable chaperone protein DnaJ2; 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 betwe [...]

grpE
Probable GrpE protein (HSP-70 cofactor); 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 [...]

dnaK
Probable chaperone protein DnaK (heat shock protein 70) (heat shock 70 kDa protein) (HSP70); Acts as a chaperone; Belongs to the heat shock protein 70 family.
  
  
 0.944
groES
10 kDa chaperonin GroES (protein CPN10) (protein GroES) (BCG-a heat shock protein) (10 kDa antigen); Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter; Belongs to the GroES chaperonin family.

hspR
Rv0353, (MTCY13E10.13), len: 126 aa. Probable hspR,heat shock regulatory protein (see Stewart et al., 2001),merR family, highly similar to others e.g. HspR|P40183 heat shock regulatory protein from Streptomyces coelicolor (151 aa), FASTA scores: E(): 4.9e-22, (55.7% identity in 140 aa overlap), that binds to three inverted repeats (IR1-IR3) in the promoter region of the dnaK operon. Has possible coiled coil region in C-terminal half. Belongs to the MerR family of transcriptional regulators.

groEL1
60 kDa chaperonin 1 GroEL1 (protein CPN60-1) (GroEL protein 1); Prevents aggregation of substrate proteins and promotes their refolding. Functions in the absence of co-chaperone CH10 and ATP.

groEL2
60 kDa chaperonin 2; Prevents aggregation of substrate proteins and promotes their refolding.

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.

rsmE
Conserved hypothetical protein; Specifically methylates the N3 position of the uracil ring of uridine 1498 (m3U1498) in 16S rRNA. Acts on the fully assembled 30S ribosomal subunit (By similarity); Belongs to the RNA methyltransferase RsmE family.
