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.

rpoBRNA polymerase (beta subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. (1193 aa)    
Predicted Functional Partners:
rplK
Ribosomal protein L11 (BL11); Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors; Belongs to the universal ribosomal protein uL11 family.
 
 0.999
rplL
Ribosomal protein L12 (BL9); Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors. Is thus essential for accurate translation.
 
 0.999
rpoC
RNA polymerase (beta' subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 0.999
rpsL
Ribosomal protein S12 (BS12); With S4 and S5 plays an important role in translational accuracy.
 
 
 0.999
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 (By similarity).
 
 
 0.999
rpoA
RNA polymerase (alpha subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 0.999
rpoZ
Omega subunit of RNA polymerase; 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 (By similarity).
  
 0.999
sigA
RNA polymerase major sigma-43 factor (sigma-A); 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; Belongs to the sigma-70 factor family. RpoD/SigA subfamily.
 
 
 0.999
rplB
Ribosomal protein L2 (BL2); One of the primary rRNA binding proteins. Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial. Makes several contacts with the 16S rRNA in the 70S ribosome. Belongs to the universal ribosomal protein uL2 family.
 
 
 0.998
nusG
Transcription antitermination factor; Participates in transcription elongation, termination and antitermination. Stimulates RNA polymerase pausing at U107 and U144 in the trp leader. NusG-stimulated pausing is sequence specific. Does not affect trp leader termination.
