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

rpoBCDNA-directed RNA polymerase subunit beta/beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. (2887 aa)    
Predicted Functional Partners:
nusA
Transcription elongation factor NusA; Participates in both transcription termination and antitermination.
 
 
 0.999
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.
 
 0.999
rpoD
RNA polymerase sigma factor RpoD; 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 primary sigma factor during exponential growth.
 
 
 0.999
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.
  
 0.999
KGL12705.1
DNA-directed RNA polymerase subunit beta/beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates; fusion of rpoB and rpoC; beta and beta' subunits are part of the catalytic core which binds with a sigma factor to produce the holoenzyme; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
0.999
rpoN
RNA polymerase sigma54 factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
  
 
 
 0.999
fliA
RNA polymerase sigma 70; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the sigma-70 factor family.
    
 
 0.999
greA
Transcription elongation factor GreA; Necessary for efficient RNA polymerase transcription elongation past template-encoded arresting sites. The arresting sites in DNA have the property of trapping a certain fraction of elongating RNA polymerases that pass through, resulting in locked ternary complexes. Cleavage of the nascent transcript by cleavage factors such as GreA or GreB allows the resumption of elongation from the new 3'terminus. GreA releases sequences of 2 to 3 nucleotides.
  
 
 0.999
rpsD
30S ribosomal protein S4; One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the body of the 30S subunit.
 
 
 0.998
nusG
Antitermination protein NusG; Participates in transcription elongation, termination and antitermination.
 
 
 0.998
