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

rpoBDNA-directed RNA polymerase beta chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. (1175 aa)    
Predicted Functional Partners:
rpoC
DNA-directed RNA polymerase beta' chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 0.999
rpoA
DNA-directed RNA polymerase alpha chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 0.999
rpoZ
Putative DNA-directed RNA polymerase omega chain; 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
DIP1974
Putative CarD-like transcriptional factor; N-terminal region is similar to Mycobacterium tuberculosis putative transcriptional factor Rv3583c TR:O53568 (EMBL:AL022075) (162 aa) fasta scores: E(): 6.8e-38, 71.69% id in 159 aa, and to Mycobacterium leprae putative transcription factor ML0320 TR:Q9CCW7 (EMBL:AL583918) (165 aa) fasta scores: E(): 1.2e-37, 70.44% id in 159 aa.
    
 
 0.999
rbpA
Conserved hypothetical protein; Binds to RNA polymerase (RNAP), stimulating transcription from principal, but not alternative sigma factor promoters. Belongs to the RNA polymerase-binding protein RbpA family.
    
 
 0.998
fusA
Elongation factor G; Catalyzes the GTP-dependent ribosomal translocation step during translation elongation. During this step, the ribosome changes from the pre-translocational (PRE) to the post-translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. Catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. EF-G/EF-2 subfamily.
 
 
 0.993
sigA
RNA polymerase sigma factor; 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.
 
 
 0.993
sigB
RNA polymerase sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
 
 
 0.993
DIP1156
Putative helicase; Similar to Streptomyces coelicolor putative helicase protein SCE59.11c SWALL:Q9L1U3 (EMBL:AL138851) (744 aa) fasta scores: E(): 5.4e-32, 34.77% id in 788 aa, and to Clostridium acetobutylicum superfamily I DNA helicase CAC1026 SWALL:AAK79002 (EMBL:AE007618) (763 aa) fasta scores: E(): 2e-15, 23.98% id in 788 aa.
    
 
 0.988
rpoE
Similar to Mycobacterium tuberculosis RNA polymerase sigma-E factor RpoE or SigH or Rv3223c or MT3320 or MTCY07D11.03 SW:RPOE_MYCTU (O05843) (216 aa) fasta scores: E(): 1e-44, 70.33% id in 182 aa; Belongs to the sigma-70 factor family. ECF subfamily.
