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

aptAdenine phosphoribosyltransferase (APRT); Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis. (170 aa)    
Predicted Functional Partners:
guaA
Fragment of conserved hypothetical protein,DUF111 family; Catalyzes the synthesis of GMP from XMP.
  
 0.992
ade
Adenine deaminase.
   
 0.983
purH
Bifunctional purine biosynthesis protein purH [Includes: Phosphoribosylaminoimidazolecarboxamide formyltransferase; IMP cyclohydrolase].
  
 0.968
PurH
5-aminoimidazole-4-carboxamide ribonucleotide transformylase.
  
 0.968
xpt
Xanthine phosphoribosyltransferase (XPRTase); Converts the preformed base xanthine, a product of nucleic acid breakdown, to xanthosine 5'-monophosphate (XMP), so it can be reused for RNA or DNA synthesis.
   
 
 0.958
purB
Adenylosuccinate lyase; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
  
 0.952
gmk
Guanylate kinase (GMP kinase); Essential for recycling GMP and indirectly, cGMP.
  
 
 0.952
pupG
Purine nucleoside phosphorylase; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate.
  
 
 0.929
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.
  
 
 0.927
hpt1
Hypoxanthine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 0.926
