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

purBPurB; Adenylosuccinate lyase; COG0015, pfam00206; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily. (451 aa)    
Predicted Functional Partners:
purA
PurA; 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.
 
 0.999
purC
PurC; Phosphoribosylaminoimidazole-succinocarboxamide synthase; pfam01259, cd01415; Belongs to the SAICAR synthetase family.
 0.999
purF
PurF; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
  
 
 0.998
purL
PurL; Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thought to assist in the transfer of the ammonia molecule f [...]

purD
PurD; Phosphoribosylamine-glycine ligase.
  
 
 0.996
purE
PurE; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
  
  
 0.996
purQ
PurQ; Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate.

purM
PurM; Phosphoribosylformylglycinamidine cyclo-ligase.
  
 
 0.990
apt
Putative adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of IMP that is energically less costly than de novo synthesis. Belongs to the purine/pyrimidine phosphoribosyltransferase family. Archaeal HPRT subfamily.
