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/guanine phosphoribosyltransferase and related PRPP-binding protein; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis. (174 aa)    
Predicted Functional Partners:
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
 0.995
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.973
amb3052
Adenylosuccinate lyase; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
  
 0.972
purH
AICAR transformylase; Only IMP cyclohydrolase domain in Aful.
  
 0.968
mtnP
Purine nucleoside phosphorylase; Catalyzes the reversible phosphorylation of S-methyl-5'- thioadenosine (MTA) to adenine and 5-methylthioribose-1-phosphate. Involved in the breakdown of MTA, a major by-product of polyamine biosynthesis. Responsible for the first step in the methionine salvage pathway after MTA has been generated from S-adenosylmethionine. Has broad substrate specificity with 6-aminopurine nucleosides as preferred substrates; Belongs to the PNP/MTAP phosphorylase family. MTAP subfamily.
 
 0.966
adk
Adenylate kinase and related 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.
  
 
 0.955
amb3473
GMP synthase - Glutamine amidotransferase domain.
  
 
 0.944
amb4308
Adenine/guanine phosphoribosyltransferase and related PRPP-binding protein; Acts on guanine, xanthine and to a lesser extent hypoxanthine.
  
 0.926
surE
Predicted acid phosphatase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.919
amb2392
Predicted pyrophosphatase.
    
  0.903
