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; Essential for recycling GMP and indirectly, cGMP. (220 aa)    
Predicted Functional Partners:
rpoZ
DNA-directed RNA polymerase, omega subunit; 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.
  
  
 0.975
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
 
 
 0.971
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.964
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
Sala_0341
Pyruvate kinase; Belongs to the pyruvate kinase family.
 
 
 0.929
Sala_2677
(p)ppGpp synthetase I, SpoT/RelA; 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.
  
 
 0.928
surE
3'-nucleotidase / 5'-nucleotidase / exopolyphosphatase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
  
  
  0.915
Sala_1773
Ribonucleoside-diphosphate reductase; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides.
    
 0.915
Sala_1775
Ribonucleoside-diphosphate reductase; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides; Belongs to the ribonucleoside diphosphate reductase small chain family.
     
 0.907
eno
Enolase; Catalyzes the reversible conversion of 2-phosphoglycerate into phosphoenolpyruvate. It is essential for the degradation of carbohydrates via glycolysis; Belongs to the enolase family.
