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

purMPhosphoribosylaminoimidazole synthetase = AIR synthetase; Residues 1 to 345 of 345 are 99.13 pct identical to residues 1 to 345 of 345 from Escherichia coli K-12 Strain MG1655: B2499; Belongs to the AIR synthase family. (345 aa)    
Predicted Functional Partners:
purN
Phosphoribosylglycinamide formyltransferase 1; 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
purL
Phosphoribosylformyl-glycineamide synthetase = FGAM synthetase; Phosphoribosylformylglycinamidine synthase involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate.
 
 
 0.999
purD
Phosphoribosylglycinamide synthetase = GAR synthetase; Residues 1 to 429 of 429 are 97.90 pct identical to residues 1 to 429 of 429 from Escherichia coli K-12 Strain MG1655: B4005; Belongs to the GARS family.
  
 0.999
purK
Phosphoribosylaminoimidazole carboxylase = AIR carboxylase, CO(2)-fixing subunit; Catalyzes the ATP-dependent conversion of 5-aminoimidazole ribonucleotide (AIR) and HCO(3)(-) to N5-carboxyaminoimidazole ribonucleotide (N5-CAIR).
 
 
 0.998
purF
Amidophosphoribosyltransferase = PRPP amidotransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine; In the C-terminal section; belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 0.998
