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

purA_1Adenylosuccinate 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. (430 aa)    
Predicted Functional Partners:
purB
Adenylosuccinate lyase; Catalyzes two discrete reactions in the de novo synthesis of purines: the cleavage of adenylosuccinate and succinylaminoimidazole carboxamide ribotide; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
 
 0.996
guaC
Guanosine 5'-monophosphate oxidoreductase; Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides; Belongs to the IMPDH/GMPR family. GuaC type 2 subfamily.
 
 
 0.993
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase; Involved in de novo purine biosynthesis; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 0.992
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.
 
 
 0.987
hpt
Hypoxanthine phosphoribosyltransferase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.952
pyrB_1
Aspartate carbamoyltransferase catalytic subunit; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
  
 
 0.932
asnB
Asparagine synthase; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 
 0.930
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
 
  
 0.914
ansA
Asparaginase; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
  
  0.913
RacX
