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.

purA,adeKAdenylosuccinate 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. (436 aa)    
Predicted Functional Partners:
purB
Adenylosuccinate lyase; Frameshift; similar to P9515_16441; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.

guaB
Putative IMP dehydrogenase; Alternative locus ID: PMED4_12081.
  
 
 0.988
purH
AICARFT/IMPCHase bienzyme:Methylglyoxal synthase-like domain; Alternative locus ID: PMED4_02711.
  
 0.984
purC
SAICAR synthetase; Alternative locus ID: PMED4_15071; Belongs to the SAICAR synthetase family.
  
 
 0.958
purE
Phosphoribosylaminoimidazole carboxylase; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
  
 
 0.953
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.
  
 
 0.948
purK
Phosphoribosylaminoimidazole carboxylase; Catalyzes the ATP-dependent conversion of 5-aminoimidazole ribonucleotide (AIR) and HCO(3)(-) to N5-carboxyaminoimidazole ribonucleotide (N5-CAIR).
  
 
 0.938
PMM0279
Conserved hypothetical protein; 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.
 
 0.937
pyrB
Aspartate carbamoyltransferase; Putative assignment; Alternative locus ID: PMED4_02381; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
  
 
 0.928
purT
GAR transformylase 2; 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.
