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

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:
purB
Fumarate lyase:Delta crystallin:Adenylosuccinate lyase; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
 
 0.993
guaB
CBS domain:IMP dehydrogenase/GMP reductase:FMN/related compound-binding core:IMP 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.
 
 
 0.984
purH
AICARFT/IMPCHase bienzyme:Methylglyoxal synthase-like domain.
  
 0.959
BAB2_0594
Fumarate lyase:Delta crystallin.
 
 0.956
guaA
GMP synthase [glutamine-hydrolyzing]; Catalyzes the synthesis of GMP from XMP.
 
  
 0.956
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
 
 
 0.900
carB
Conserved hypothetical protein; Belongs to the CarB family.
 
 
 0.883
glyA
Glycine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
  
  
 0.878
purC
SAICAR synthetase.
  
 0.877
purD
Phosphoribosylglycinamide synthetase; Belongs to the GARS family.
  
 
 0.875
