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.

purAAdenylosuccinate 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. (429 aa)    
Predicted Functional Partners:
SB4_07115
Adenylosuccinate lyase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
 
 0.999
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase; Involved in de novo purine biosynthesis; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 0.998
guaB
Inosine-5-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
 
 
 0.994
purC
Phosphoribosylaminoimidazole-succinocarboxamide synthase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the SAICAR synthetase family.
  
 
 0.978
purE
N5-carboxyaminoimidazole ribonucleotide mutase; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
  
 
 0.977
purK
Phosphoribosylaminoimidazole carboxylase; Catalyzes the ATP-dependent conversion of 5-aminoimidazole ribonucleotide (AIR) and HCO(3)(-) to N5-carboxyaminoimidazole ribonucleotide (N5-CAIR).
  
 
 0.962
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
 
  
 0.959
pyrB
Aspartate carbamoyltransferase catalytic subunit; Catalyzes the transfer of the carbamoyl moiety from carbamoyl phosphate to L- aspartate in pyrimidine biosynthesis; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
 
 
 0.952
SB4_07830
Nucleoside-triphosphate diphosphatase; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family.
 
 0.951
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.
