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

sigARNA 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. (502 aa)    
Predicted Functional Partners:
EFL24083.1
DNA-directed RNA polymerase, beta' subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.999
rpoB
DNA-directed RNA polymerase, beta subunit; 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 subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.996
rbpA
Putative membrane-associated GTPase; Binds to RNA polymerase (RNAP), stimulating transcription from principal, but not alternative sigma factor promoters.
  
 
 
 0.989
rpoZ
DNA-directed RNA polymerase, omega subunit; 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.
   
 
 0.985
EFL26229.1
Ferric uptake regulation protein; Belongs to the Fur family.
  
 
 0.971
EFL25126.1
CarD family transcriptional regulator.
   
 
 0.963
EFL25298.1
Transcriptional regulator.
   
 
 0.957
whiB
WhiB family transcription factor; Acts as a transcriptional regulator. Probably redox- responsive. The apo- but not holo-form probably binds DNA.
    
 
 0.920
EFL28200.1
AraC family transcriptional regulator.
    
 
 0.904
