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

purHProbable bifunctional purine biosynthesis purh [includes:phosphoribosylaminoimidazolecarboxamide formyltransferase (aicar transformylase); imp cyclohydrolase (inosinicase) (imp synthetase) (atic)]. transmembrane protein. (524 aa)    
Predicted Functional Partners:
purN
Probable phosphoribosylglycinamide formyltransferase protein; 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.
 0.999
purD
Probable phosphoribosylamine--glycine ligase (gars) (glycinamideribonucleotide synthetase) (phosphoribosylglycinamide synthetase) protein.
 
 
 0.987
purF
Probable amidophosphoribosyltransferase protein; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine; In the C-terminal section; belongs to the purine/pyrimidine phosphoribosyltransferase family.
 
 
 0.986
purM
Probable phosphoribosylformylglycinamidine cyclo-ligase (airs)(phosphoribosyl-aminoimidazole synthetase) (air synthase) protein.
 
  
 0.986
purE
Probable phosphoribosylaminoimidazole carboxylase catalytic subunit protein; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
 
  
 0.985
purB
Probable adenylosuccinate lyase protein; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
  
 0.983
purA
Probable adenylosuccinate synthetase (imp--aspartate ligase)(adss) (ampsase) protein; 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.
  
 0.981
folD
Methenyltetrahydrofolate cyclohydrolase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
  
 
 0.979
glyA1
Probable serine hydroxymethyltransferase 1 (serine methylase 1)(shmt 1) protein; 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.
  
 0.977
guaB
Probable inosine-5'-monophosphate dehydrogenase oxidoreductase protein; 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.
