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. (333 aa)    
Predicted Functional Partners:
rpoB
DNA-directed RNA polymerase, beta subunit, RpoB; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.996
rpoC
DNA-directed RNA polymerase, beta chain, RpoC; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.993
rpoA
DNA-directed RNA polymerase (alpha chain), RpoA; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.990
rbpA
Conserved hypothetical protein; Binds to RNA polymerase (RNAP), stimulating transcription from principal, but not alternative sigma factor promoters. Belongs to the RNA polymerase-binding protein RbpA family.
    
 
 0.987
rpoZ
DNA-directed RNA polymerase (omega chain) RpoZ; 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.
   
 
 0.975
MMAR_5083
Conserved transcriptional regulatory protein; Function unknown role in regulation.
   
 
 0.950
ideR
Transcriptional regulatory protein (repressor and activator), iron-binding repressor of siderophore biosynthesis and iron uptake. seems to regulate a variety of genes encoding a variety of proteins E.G. transporters, proteins involved in siderophore synthesis and iron storage, members of the PE/PPE family, enzymes involved in lipid metabolism, transcriptional regulatory proteins, etc. also activator of BfrA gene.
  
  
 0.891
whiB1
Transcriptional regulatory protein Whib-like WhiB1; Acts as a transcriptional regulator. Probably redox- responsive. The apo- but not holo-form probably binds DNA.
    
 
 0.814
whiB7
Transcriptional regulatory protein Whib-like WhiB7; Acts as a transcriptional regulator. Probably redox- responsive. The apo- but not holo-form probably binds DNA.
    
 
 0.795
dnaG
DNA primase DnaG; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.
 
  
 0.786
