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.

rpoZDNA-directed RNA polymerase, omega chain (rpoZ); 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). (88 aa)    
Predicted Functional Partners:
rpoA
DNA-directed RNA polymerase, alpha chain (rpoA); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 0.998
rpoB
DNA-directed RNA polymerase, beta chain (rpoB); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 0.996
rpoC
DNA-directed RNA polymerase, beta' chain (rpoC); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 0.994
rpoD
RNA polymerase sigma-70 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.
  
 
 
 0.980
nusG
Transcription antitermination protein (nusG); Participates in transcription elongation, termination and antitermination.
  
 
 0.942
rapA
ATP-dependent helicase (hepA); Transcription regulator that activates transcription by stimulating RNA polymerase (RNAP) recycling in case of stress conditions such as supercoiled DNA or high salt concentrations. Probably acts by releasing the RNAP, when it is trapped or immobilized on tightly supercoiled DNA. Does not activate transcription on linear DNA. Probably not involved in DNA repair; Belongs to the SNF2/RAD54 helicase family. RapA subfamily.
    
  0.941
rpsB
Ribosomal protein S2 (rpS2); Similar to GB:D26562 SP:P02351 GB:V00343 PID:42842 PID:473824 percent identity: 82.16; identified by sequence similarity; putative; Belongs to the universal ribosomal protein uS2 family.
  
 
 0.936
dksA
dnaK suppressor protein (dksA); Transcription factor that acts by binding directly to the RNA polymerase (RNAP). Required for negative regulation of rRNA expression and positive regulation of several amino acid biosynthesis promoters. Also required for regulation of fis expression.
 
 
 
 0.918
gmk
Guanylate kinase (gmk); Essential for recycling GMP and indirectly, cGMP.
  
  
 0.918
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 (By similarity).
