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. (191 aa)    
Predicted Functional Partners:
apt
Putative adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.967
hprT
Hypoxanthine-guanine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
    
 0.952
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
 
 0.948
guaC
Guanosine 5'-monophosphate oxidoreductase; 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. Belongs to the IMPDH/GMPR family. GuaC type 2 subfamily.
    
 0.934
pyk
Pyruvate kinase; Belongs to the pyruvate kinase family.
  
 
 0.932
hpt
Putative hypoxanthine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
    
 0.932
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. 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.
  
 
 0.928
APE74350.1
Putative N-6 adenine-specific DNA methylase.
      0.920
adk
Adenylate kinase; Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. Plays an important role in cellular energy homeostasis and in adenine nucleotide metabolism; Belongs to the adenylate kinase family.
   
 
 0.901
rsmB
Putative ribosomal RNA small subunit methyltransferase; Specifically methylates the cytosine at position 967 (m5C967) of 16S rRNA.
 
 
 0.855
