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

AMK19731.1RNA polymerase factor sigma-54; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (502 aa)    
Predicted Functional Partners:
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.
  
 
 
 0.930
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.
 
 
 0.930
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.
    
 
 0.923
rpoZ
DNA-directed RNA polymerase subunit omega; 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.
   
 
 0.856
AMK19506.1
Psp operon transcriptional activator; COG1221 Transcriptional regulators containing an AAA-type ATPase domain and a DNA-binding domain.
 
   
 0.837
AMK19006.1
CheY-like response regulator; COG3829 Transcriptional regulator containing PAS, AAA-type ATPase, and DNA-binding domains.
 
   
 0.793
ntrC
Two-component system response regulator GnG/NtrC; Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Phosphorylated NtrC binds directly to DNA and stimulates the formation of open promoter-sigma54-RNA polymerase complexes.
 
   
 0.792
AMK18834.1
Two-component system response regulator HydG; COG2204 Response regulator containing CheY-like receiver, AAA-type ATPase, and DNA-binding domains.
 
   
 0.789
AMK17888.1
Fis family two component sigma-54 specific transcriptional regulator; COG2204 Response regulator containing CheY-like receiver, AAA-type ATPase, and DNA-binding domains.
 
   
 0.776
AMK17543.1
Fis family two component sigma-54 specific transcriptional regulator; COG2204 Response regulator containing CheY-like receiver, AAA-type ATPase, and DNA-binding domains.
