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

SDN42848.1RNA polymerase sigma-B factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (262 aa)    
Predicted Functional Partners:
rsbW
Serine/threonine-protein kinase RsbW; Negative regulator of sigma-B activity. Phosphorylates and inactivates its specific antagonist protein, RsbV. Upon phosphorylation of RsbV, RsbW is released and binds to sigma-B, thereby blocking its ability to form an RNA polymerase holoenzyme (E-sigma-B).
 
 0.999
SDN42745.1
sigma-B regulation protein RsbU (phosphoserine phosphatase).
 
 
 0.944
SDN42774.1
Anti-sigma B factor antagonist; Belongs to the anti-sigma-factor antagonist family.
 
  
 0.942
SDO02812.1
Negative regulator of flagellin synthesis FlgM.
  
 0.934
SDN63372.1
Stage II sporulation protein AA (anti-sigma F factor antagonist); Belongs to the anti-sigma-factor antagonist family.
 
  
 0.878
SDN42883.1
Negative regulator of sigma-B (phosphoserine phosphatase).
 
 
 0.874
spoIIAB
Stage II sporulation protein AB (anti-sigma F factor); Binds to sigma F and blocks its ability to form an RNA polymerase holoenzyme (E-sigma F). Phosphorylates SpoIIAA on a serine residue. This phosphorylation may enable SpoIIAA to act as an anti- anti-sigma factor that counteracts SpoIIAB and thus releases sigma F from inhibition.
 
 
 0.835
SDN01734.1
Flagellar motor switch protein FliN/FliY.
  
  
 0.816
SDN42710.1
Serine/threonine-protein kinase RsbT.
  
 
 0.812
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.
    
 
 0.783
