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

rpoDRNA 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. (616 aa)    
Predicted Functional Partners:
rpoB
DNA-directed RNA polymerase beta subunit RpoB; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.993
rpoA
DNA-directed RNA polymerase alpha subunit RpoA; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.989
rpoZ
DNA-directed RNA polymerase omega subunit 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.
 
 
 
 0.984
rsd
Regulator of sigma D Rsd; Belongs to the Rsd/AlgQ family.
   
 
 0.979
rpoC
DNA-directed RNA polymerase beta' subunit RpoC; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.977
dnaG
DNA primase DnaG; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.
  
 0.959
nusA
N utilization substance protein A NusA; Participates in both transcription termination and antitermination.
 
 
 0.941
sspA
Transcpriptional activator SspA; Belongs to the GST superfamily.
    
 
 0.923
gyrB
DNA gyrase B subunit GyrB; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.
 
 
 0.891
crp
cAMP-responsive regulator of catabolite repression Crp.
    
 
 0.878
