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

purHPFAM: AICARFT/IMPCHase bienzyme; MGS-like domain; TIGRFAM: phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase. (499 aa)    
Predicted Functional Partners:
purN
Phosphoribosylglycinamide formyltransferase, formyltetrahydrofolate-dependent; 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
purM
Phosphoribosylaminoimidazole synthetase; PFAM: AIR synthase related protein, N-terminal domain; AIR synthase related protein, C-terminal domain; TIGRFAM: phosphoribosylaminoimidazole synthetase.
 
  
 0.989
AEX85987.1
PFAM: Lyase; Adenylosuccinate lyase C-terminus; TIGRFAM: adenylosuccinate lyase; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
  
 0.989
purD
Phosphoribosylamine--glycine ligase; PFAM: Phosphoribosylglycinamide synthetase, N domain; Phosphoribosylglycinamide synthetase, ATP-grasp (A) domain; Phosphoribosylglycinamide synthetase, C domain; TIGRFAM: phosphoribosylamine--glycine ligase; Belongs to the GARS family.
 
 
 0.988
purC
PFAM: SAICAR synthetase; TIGRFAM: phosphoribosylaminoimidazole-succinocarboxamide synthase.
 
 
 0.987
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
 
 
 0.987
glyA
Glycine/serine 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.
  
 0.986
fhs
Formyltetrahydrofolate synthetase; PFAM: Formate--tetrahydrofolate ligase; Belongs to the formate--tetrahydrofolate ligase family.
  
 0.984
purE
Phosphoribosylcarboxyaminoimidazole (NCAIR) mutase; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
 
  
 0.977
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 [...]
