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

rpoSRNA polymerase, sigma 70 subunit, RpoD subfamily; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response. (346 aa)    
Predicted Functional Partners:
rpoA
DNA-directed RNA polymerase subunit alpha; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.976
rpoB
DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.965
rpoC
DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.957
rpoZ
DNA-directed RNA polymerase subunit omega; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
   
 
 0.952
EGZ45709.1
KEGG: tgr:Tgr7_1457 transcriptional regulator, MerR family; PFAM: HTH transcriptional regulator, MerR; SMART: HTH transcriptional regulator, MerR.
  
 
 0.941
dnaG
DNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.
  
 0.925
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 [...]
  
 
 0.890
nusA
NusA antitermination factor; Participates in both transcription termination and antitermination.
 
 
 0.885
EGZ49863.1
KEGG: slt:Slit_0286 diguanylate phosphodiesterase; PFAM: Diguanylate phosphodiesterase, EAL domain; Cyclic nucleotide-binding domain; SMART: Diguanylate phosphodiesterase, EAL domain; Cyclic nucleotide-binding domain.
    
 
 0.866
dnaK
Chaperone protein dnaK; Acts as a chaperone; Belongs to the heat shock protein 70 family.
  
 
 0.815
