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

spoTRelA/SpoT family protein; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. (735 aa)    
Predicted Functional Partners:
relA
GTP pyrophosphokinase, (p)ppGpp synthetase I; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance.
  
  
 
0.923
pyk
Pyruvate kinase; Belongs to the pyruvate kinase family.
  
 
 0.914
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.911
ppx
Exopolyphosphatase; Belongs to the GppA/Ppx family.
   
 
 0.911
ndk
Nucleoside diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
    
 0.907
nrdD
Ribonucleotide reductase of class III (anaerobic), large subunit.
     
  0.900
NrdB
Ribonucleotide reductase of class Ia (aerobic), beta subunit.
     
  0.900
nrdA
Ribonucleotide reductase of class Ia (aerobic), alpha subunit.
     
  0.900
rpsF
SSU ribosomal protein S6p; Binds together with S18 to 16S ribosomal RNA.
  
   0.807
rpoZ
DNA-directed RNA polymerase omega subunit; 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.
     
 0.801
