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

KKF37337.1RNA polymerase factor sigma-54; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (477 aa)    
Predicted Functional Partners:
pspF
Phage shock protein; Transcriptional activator for pspABCE which are induced in response to phage proteins, membrane altering stresses, and impaired proton expor; Derived by automated computational analysis using gene prediction method: Protein Homology.

 0.986
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.
  
 
 0.963
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.

KKF37936.1
PTS system nitrogen regulatory protein IIA(Ntr); Involved in nitrogen metabolism; protein IIA is phosphorylated by enzyme I(Ntr); Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.886
glnG
Nitrogen regulation protein NR(I); 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.
