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

purB1Adenylosuccinate lyase; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily. (431 aa)    
Predicted Functional Partners:
purC
Phospho ribosylaminoimidazole-succinocarboxamide synthase; Belongs to the SAICAR synthetase family.
 
 0.993
purA
Adenylosuccinate synthetase (IMP-aspartate ligase); 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.
 
 0.989
purH
Bifunctional protein:phospho ribosylaminoimidazole carboxamide formyltransferase (AICAR transformylase)and IMP cyclohydrolase (inosinicase).
  
 0.988
apt
Adenine phosphoribosyltransferase (APRT); Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 0.954
purE
Phospho ribosylaminoimidazole carboxylase (AIR carboxylase), catalytic subunit; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
  
  
 0.949
adk
Adenylate kinase (ATP-AMP transphosphorylase); 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.
   
 0.934
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine; In the C-terminal section; belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.907
purD
Phosphoribosylamine--glycine ligase (Phosphoribosylglycinamide synthetase); Belongs to the GARS family.
  
 
 0.904
purM
Phospho ribosylformylglycinamidine cyclo-ligase.
  
 
 0.903
purB2
Adenylosuccinate lyase; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
  
  
 
0.901
