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

purCPhosphoribosylaminoimidazolesuccinocarboxamide synthase; Function Code:4.01 - Nucleotide Metabolism, Purine metabolism; similar to, pir:LN:G64498 AC:G64498, p()=1.6E-65, pid=46%; Belongs to the SAICAR synthetase family. (248 aa)    
Predicted Functional Partners:
purE
Phosphoribosylaminoimidazole carboxylase; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
 
 0.999
purD
Glycinamide ribonucleotide synthetase; Function Code:4.01 - Nucleotide Metabolism, Purine metabolism; similar to, pir:LN:A64417 AC:A64417, p()=9E-120, pid=53%.

purQ
Phosphoribosylformylglycinamidine synthase I; 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 i [...]

purM
Phosphoribosylformylglycinamidine cyclo-ligase; Function Code:4.01 - Nucleotide Metabolism, Purine metabolism; similar to, sp:LN:PUR5_METJA AC:Q57656, p()=2.6E-81, pid=47%.

purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
 
 
 0.998
purA
Adenylosuccinate 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.
  
 
 0.913
glyA
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydromethanopterin (H4MPT) serving as the one-carbon carrier. Cannot use tetrahydrofolate (THF or H4PteGlu) instead of H4MPT as the pteridine substrate. Also probably exhibits a pteridine- independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
