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

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. (745 aa)    
Predicted Functional Partners:
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.
 
 
 0.972
rpsF
30S ribosomal protein S6; Binds together with S18 to 16S ribosomal RNA.
  
 
 0.938
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.
 
 
 0.936
rplJ
50S ribosomal protein L10; Forms part of the ribosomal stalk, playing a central role in the interaction of the ribosome with GTP-bound translation factors. Belongs to the universal ribosomal protein uL10 family.
  
   0.931
rplX
50S ribosomal protein L24; One of the proteins that surrounds the polypeptide exit tunnel on the outside of the subunit.
  
   0.922
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
ppx
Exopolyphosphatase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the GppA/Ppx family.
  
 
 0.919
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.
  
  
 
0.917
pykF
Pyruvate kinase; Catalyzes the formation of phosphoenolpyruvate from pyruvate; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 
 0.917
rplK
50S ribosomal protein L11; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors.
   
 
 0.911
