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

rpoZDNA-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. (118 aa)    
Predicted Functional Partners:
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.
  
 0.999
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
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.
  
 0.998
rbpA
Hypothetical protein; Binds to RNA polymerase (RNAP), stimulating transcription from principal, but not alternative sigma factor promoters.
  
 
   0.986
gmk
Guanylate kinase, Guanosine monophosphate kinase (GMP kinase); Essential for recycling GMP and indirectly, cGMP.
  
  
 0.986
hepA
Helicase (SNF2-related protein).
    
 0.974
carD
Transcriptional regulator CarD; Probably regulates isp genes.
  
 
 0.971
hrdB
RNA polymerase principal sigma factor HrdB; 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.
   
 
 0.967
hrdD2
RNA polymerase principal sigma factor HrdD; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
   
 
 0.967
dinG
Probable helicase involved in DNA repair and perhaps also replication.
    
 0.967
