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.

purBAdenylosuccinate lyase; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily. (433 aa)    
Predicted Functional Partners:
purC
Phosphoribosylaminoimidazole-succinocarboxamide synthase; Belongs to the SAICAR synthetase family.
 0.999
purA
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.
 
 0.998
purH
Bifunctional purine biosynthesis protein, phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase.
  
 0.996
purK
Phosphoribosylaminoimidazole carboxylase, ATPase subunit; Catalyzes the ATP-dependent conversion of 5-aminoimidazole ribonucleotide (AIR) and HCO(3)(-) to N5-carboxyaminoimidazole ribonucleotide (N5-CAIR).
  
 
 0.990
purM
Phosphoribosyl formylglycinamidine cyclo-ligase.
  
 
 0.990
purE
Phosphoribosylaminoimidazole carboxylase; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
  
 
 0.990
purF
Amidophosphoribosyl transferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
  
 
 0.989
purD
Phosphoribosylglycinamide synthetase; Belongs to the GARS family.
  
 
 0.988
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 0.977
purN
Phosphoribosylglycinamide formyltransferase; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate.
