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

ABD31332.1Sigma factor B, putative; 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
Anti-sigma B factor, putative; 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) (By similarity).
 
 
 0.999
rsbV
STAS domain, putative; Positive regulator of sigma-B activity. Non-phosphorylated RsbV binds to RsbW, preventing its association with sigma-B. When phosphorylated, releases RsbW, which is then free to complex with and inactivate sigma-B (By similarity); Belongs to the anti-sigma-factor antagonist family.
 
 
 0.998
ABD31335.1
sigmaB regulation protein RsbU, putative.
 
 
 0.918
mazE
Conserved hypothetical protein; Antitoxin component of a type II toxin-antitoxin (TA) system. Labile antitoxin that binds to cognate MazF toxin and counteracts its endoribonuclease activity; Belongs to the MazE/EndoAI family.
     
 0.835
rpoB
RNA polymerase beta chain, putative; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.803
ABD31336.1
sigmaB regulation protein RsbU, putative.
  
 
 0.802
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.
    
 
 0.801
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.
  
 
 
 0.764
mazF
Conserved hypothetical protein; Toxic component of a type II toxin-antitoxin (TA) system. Ribosome-independent, sequence-specific endoribonuclease that cleaves mRNA, thus inhibiting protein synthesis and inducing bacterial stasis. It cuts between the first and nucleotides of 5'-UACAU-3' in single- stranded RNA. Neutralized by coexpression with cognate antitoxin MazE. Belongs to the PemK/MazF family.
 
   
 0.654
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.
