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. (207 aa)    
Predicted Functional Partners:
guaA
GMP synthetase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
 
 
 0.982
spoT
(p)ppGpp synthetase II; 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. This enzyme catalyzes the degradation of ppGpp into GDP. It may also be capable of catalyzing the synthesis of ppGpp (By similarity); Belongs to the RelA/SpoT family.
  
 
 0.964
rpoZ
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 (By similarity).
  
  
 0.955
gpt
Guanine-hypoxanthine phosphoribosyltransferase; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily.
  
 
 0.939
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.939
hpt
Hypoxanthine phosphoribosyltransferase; Residues 1 to 182 of 182 are 100.00 pct identical to residues 1 to 182 of 182 from Escherichia coli K-12 Strain MG1655: B0125; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
  
 0.930
pykF
Pyruvate kinase I (formerly F), fructose stimulated; Residues 1 to 470 of 470 are 100.00 pct identical to residues 1 to 470 of 470 from Escherichia coli K-12 Strain MG1655: B1676.
 
 
 0.929
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.
   
 0.927
pykA
Pyruvate kinase II, glucose stimulated; Residues 1 to 480 of 480 are 99.58 pct identical to residues 1 to 480 of 480 from Escherichia coli K-12 Strain MG1655: B1854; Belongs to the pyruvate kinase family.
 
 
 0.926
guaC
GMP reductase; Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides.
    
 0.916
