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

rpoNRNA polymerase sigma-54 factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (488 aa)    
Predicted Functional Partners:
rpoS
RNA polymerase sigma factor RpoS; 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 master transcriptional regulator of the stationary phase and the general stress response.

luxO
AAA family ATPase; Acts negatively to control the expression of luminescence. At low cell density, LuxO is phosphorylated, and together with sigma-54, causes repression of the luxCDABEGH operon. This repression could be indirect, LuxO could activate a negative regulator of luminescence. At high cell density, LuxO is dephosphorylated and inactive, therefore the luxCDABEGH operon is not repressed and light is emitted. LuxO and sigma-54 have also a role in activating the production of siderophore and in regulating the rugose colony morphology phenotype (By similarity).

AMG00519.1
RNA polymerase subunit sigma-70; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
   
 
 0.920
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.
  
 
 0.908
rpoZ
DNA-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.

ptsN
PTS sugar transporter; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.881
glnG
Nitrogen regulation protein NR(I); Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Phosphorylated NtrC binds directly to DNA and stimulates the formation of open promoter-sigma54-RNA polymerase complexes.
 
   
 0.880
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.
    
 
 0.877
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; beta subunit is part of the catalytic core which binds with a sigma factor to produce the holoenzyme; Derived by automated computational analysis using gene prediction method: Protein Homology.

AMF97567.1
YhbH; resting ribosome-binding protein involved in ribosome stabilization and preservation in stationary phase; binds specifically 100S ribosomes (an inactive ribosome product of a 70S ribosome dimerization); seems to be involved in modulation of the sigma(54) (RpoN) activity for quorum sensing; Derived by automated computational analysis using gene prediction method: Protein Homology.
