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

sigBRNA polymerase sigma factor SigB; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (256 aa)    
Predicted Functional Partners:
rsbW
Serine/threonine protein kinase; 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).
 
 
 0.996
rsbV
anti-sigma-B factor antagonist; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the anti-sigma-factor antagonist family.
 
 
 0.992
rsbU
Serine/threonine protein phosphatase; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
 
 0.980
AKS73146.1
Antitoxin MazE; Derived by automated computational analysis using gene prediction method: Protein Homology.
     
 0.881
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.
    
 
 0.814
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.
    
 
 0.811
AKS73147.1
PemK family transcriptional regulator; Toxic component of a type II toxin-antitoxin (TA) system.
 
   
 0.804
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.

Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
    0.629
alr
Alanine racemase; Catalyzes the interconversion of L-alanine and D-alanine. May also act on other amino acids; Belongs to the alanine racemase family.
