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

gmkGuanylate kinase, Guanosine monophosphate kinase (GMP kinase); Essential for recycling GMP and indirectly, cGMP. (206 aa)    
Predicted Functional Partners:
guaA
GMP synthase [glutamine-hydrolyzing] (Glutamine amidotransferase) (GMP synthetase); Catalyzes the synthesis of GMP from XMP.
 
 
 0.993
rpoZ
DNA-directed RNA polymerase subunit omega; 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.
  
  
 0.986
apt
Adenine phosphoribosyltransferase (AMP:diphosphate phospho-D-ribosyltransferase); Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.968
hpt
Guanine and 6-mercaptopurine can replace hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
     
 0.963
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.
   
 0.936
pyk1
Pyruvate kinase 1; ATP + Pyruvate <=> ADP + Phosphoenolpyruvate; Belongs to the pyruvate kinase family.
 
 
 0.930
lepA
GTP-binding protein LepA; Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre- translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP- dependent manner.
 
  
 0.926
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
guA
Glutamine amidotransferase class-I; ATP + xanthosine 5 prime-phosphate + L-glutamine + H2O = AMP + diphosphate + GMP + L-glutamate; inhibiteur Psicofuranin.
  
 
 0.914
aroE
Shikimate + NADP+ <=> 3-Dehydroshikimate + NADPH + H+ and Shikimate + NADP+ <=> 5-Dehydroshikimate + NADPH.
  
 
 0.913
