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

sigLRNA polymerase sigma-54 factor (sigma-L); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of the levanase operon. The open complex (sigma-54 and core RNA polymerase) serves as the receptor for receipt of the melting signal from the remotely bound activator protein LevR for the expression of the levanase operon. (436 aa)    
Predicted Functional Partners:
levR
Transcriptional regulator (NifA/NtrC family); Involved in positive regulation of the levanase operon which comprises the levDEFG genes for a fructose PTS system, and sacA for levanase.
 
 
 
 0.985
yplP
Transcriptional enhancer; May play a role in cold adaptation.
 
 
 0.982
acoR
Transcriptional regulator; Acts as a transcriptional activator of the acoABCL operon encoding the acetoin dehydrogenase complex.
 
  
 0.980
bkdR
Transcriptional regulator; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: regulator.
 
   
 0.968
rocR
Transcriptional regulator (NtrC/NifA family); Positive regulator of arginine catabolism. Controls the transcription of the two operons rocABC and rocDEF and probably acts by binding to the corresponding upstream activating sequences.
 
   
 0.968
rpoA
RNA polymerase (alpha subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.892
rpoB
RNA polymerase (beta subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.882
rpoC
RNA polymerase (beta' subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.881
sigH
RNA polymerase sigma-30 factor (sigma(H)); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in the transition to post- exponential phase in the beginning of sporulation. It is also required for transcription of several stationary phase genes.
   
  
 0.880
rpoZ
Omega subunit of RNA polymerase; 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 (By similarity).
   
 
 0.854
