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

spoT(p)ppGpp synthetase; 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. (706 aa)    
Predicted Functional Partners:
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.968
mazG
Nucleoside triphosphate hydrolase; Functions in degradation of stringent response intracellular messenger ppGpp; in Escherichia coli this gene is co-transcribed with the toxin/antitoxin genes mazEF; activity of MazG is inhibited by MazEF in vitro; ppGpp inhibits mazEF expression; MazG thus works in limiting the toxic activity of the MazF toxin induced during starvation; MazG also interacts with the GTPase protein Era; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 
 0.924
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.
    
 0.920
gppA
Guanosine polyphosphate pyrophosphohydrolase; 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.
  
 
 0.919
ppx
Exopolyphosphatase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the GppA/Ppx family.
  
 
 0.919
AKL35665.1
Pyruvate kinase; Catalyzes the formation of phosphoenolpyruvate from pyruvate; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 
 0.919
pykF
Pyruvate kinase; Catalyzes the formation of phosphoenolpyruvate from pyruvate; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 
 0.918
relA
(p)ppGpp synthetase; 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.
  
  
 
0.917
cyaA
Adenylate cyclase; Catalyzes transfer of adenylyl group of ATP from pyrophosphate to the 3'-hydroxyl group to form cyclic AMP; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the adenylyl cyclase class-1 family.
     
 0.903
AKL34860.1
Hypothetical protein; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides.
     
 0.902
