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.

purKPhosphoribosylaminoimidazole carboxylase (NCAIR synthetase); Catalyzes the ATP-dependent conversion of 5-aminoimidazole ribonucleotide (AIR) and HCO(3)(-) to N5-carboxyaminoimidazole ribonucleotide (N5-CAIR). (395 aa)    
Predicted Functional Partners:
purE
Phosphoribosylaminoimidazole carboxylase catalytic subunit PurE; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
 0.999
purC
Phosphoribosylaminoimidazolesuccinocarboxamide synthase; Belongs to the SAICAR synthetase family.
 
 
 0.998
BPSY_1331
Adenylosuccinate lyase.
  
 
 0.992
purM
Phosphoribosylformylglycinamidine cyclo-ligase.
 
 
 0.989
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine; In the C-terminal section; belongs to the purine/pyrimidine phosphoribosyltransferase family.
 
 
 0.989
BPSY_1270
Purl.
  
  
 0.987
purH
Bifunctional phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase.
 
  
 0.951
purT
Phosphoribosylglycinamide formyltransferase; Involved in the de novo purine biosynthesis. Catalyzes the transfer of formate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR). Formate is provided by PurU via hydrolysis of 10-formyl-tetrahydrofolate; Belongs to the PurK/PurT family.
  
 
0.946
purA
Adenylosuccinate synthase; 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.
  
 
 0.937
purD
Phosphoribosylamine--glycine ligase; Belongs to the GARS family.
 
  
 0.908
