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

Score
gmkGuanylate kinase; Essential for recycling GMP and indirectly, cGMP. (215 aa)    
Predicted Functional Partners:
guaA
GMP synthetase (glutamine aminotransferase); Catalyzes the synthesis of GMP from XMP.
 
 
 0.974
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.971
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.
  
  
 0.941
XM1_4496
Homologs of previously reported genes of unknown function.
  
  
 0.934
ndk
Nucleoside diphosphate kinase ndk; 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.
  
 0.931
spoT
Bifunctional (p)ppGpp synthetase II and guanosine-3',5'-bis pyrophosphate 3'-pyrophosphohydrolase; 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.
  
 
 0.930
XM1_1665
Putative Glutamine amidotransferase(Glutamine amidotransferase type 1,44-182); Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
  
 
 0.923
pyk
Pyruvate kinase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the pyruvate kinase family.
  
 
 0.923
gpt
Guanine-hypoxanthine phosphoribosyltransferase; Acts on guanine, xanthine and to a lesser extent hypoxanthine.
   
 0.920
surE
Broad specificity 5'(3')-nucleotidase and polyphosphatase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
