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 factor, putative; 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. (368 aa)    
Predicted Functional Partners:
rpoB
RNA polymerase beta chain, putative; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.978
rpoA
DNA-directed RNA polymerase alpha chain, putative; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.977
rpoC
DNA directed RNA polymerase beta-prime chain, putative; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.969
dnaG
DNA primase, putative; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.
  
 0.964
rpoZ
Conserved hypothetical protein; 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.
  
 
 0.958
dnaK
DNAk protein, putative; Acts as a chaperone; Belongs to the heat shock protein 70 family.
  
 
 0.787
nusA
Transcription termination-antitermination factor, putative; Participates in both transcription termination and antitermination.
  
 
 0.784
fur
Conserved hypothetical protein; Acts as a global negative controlling element, employing Fe(2+) as a cofactor to bind the operator of the repressed genes.
  
 
 0.784
spxA
Conserved hypothetical protein; Interferes with activator-stimulated transcription by interaction with the RNA polymerase alpha-CTD. May function to globally reduce transcription of genes involved in growth- and development- promoting processes and to increase transcription of genes involved in thiol homeostasis, during periods of extreme stress. Belongs to the ArsC family. Spx subfamily.
