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

aptPhosphoribosyl transferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis. (171 aa)    
Predicted Functional Partners:
guaA
Glutamine amidotransferase class-I:GMP synthase; Catalyzes the synthesis of GMP from XMP.
  
 0.992
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.959
purH
AICARFT/IMPCHase bienzyme:Methylglyoxal synthase-like domain; Alternative locus ID: PMED4_02711.
  
 0.957
purB
Adenylosuccinate lyase; Frameshift; similar to P9515_16441; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
  
 0.957
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.
  
 
 0.943
surE
Survival protein SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.914
hisF
Imidazole glycerol phosphate synthase subunit HisF (cyclase); IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit.
   
 
 0.820
hisH
Glutamine amidotransferase class-I; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisH subunit catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the synthesis of IGP and AICAR. The resulting ammonia molecule is channeled to the active site of HisF.
   
 
  0.805
PMM1565
Prephenate dehydrogenase; Conserved hypothetical assignment; Alternative locus ID: PMED4_17751.
  
    0.570
purA,adeK
Adenylosuccinate synthetase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.
