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

spoTBifunctional (p)ppGpp synthase/hydrolase SpoT; 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. (708 aa)    
Predicted Functional Partners:
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.961
mazG
Nucleoside triphosphate pyrophosphohydrolase.
  
 
 0.918
relA
GTP pyrophosphokinase; 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.
  
  
 
0.915
gppA
ppx/GppA phosphatase family protein; Catalyzes the conversion of pppGpp to ppGpp. Guanosine pentaphosphate (pppGpp) is a cytoplasmic signaling molecule which together with ppGpp controls the 'stringent response', an adaptive process that allows bacteria to respond to amino acid starvation, resulting in the coordinated regulation of numerous cellular activities.
  
 
 0.913
ppx
Exopolyphosphatase; Belongs to the GppA/Ppx family.
  
 
 0.913
ndk
Nucleoside diphosphate kinase.
    
 0.913
pyk
Pyruv_kin: pyruvate kinase; Belongs to the pyruvate kinase family.
   
 
 0.901
pyk-2
Pyruv_kin: pyruvate kinase; Belongs to the pyruvate kinase family.
   
 
 0.901
pyk-3
Pyruv_kin: pyruvate kinase; Belongs to the pyruvate kinase family.
   
 
 0.901
nrdE2
Ribonucleoside-diphosphate reductase, alpha subunit; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides.
