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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

purHBifunctional purine biosynthesis protein PurH; KEGG: gsu:GSU0609 phosphoribosylaminoimidazolecarboxamide formyltransferase (521 aa)    
Predicted Functional Partners:
purN
Phosphoribosylglycinamide formyltransferase; 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
Phosphoribosylamine--glycine ligase; KEGG: gme:Gmet_2904 phosphoribosylglycinamide synthetase; TIGRFAM: phosphoribosylamine--glycine ligase; PFAM: phosphoribosylglycinamide synthetase; Belongs to the GARS family
 
 
 0.998
Ppro_1145
TIGRFAM: adenylosuccinate lyase; PFAM: fumarate lyase; KEGG: bms:BR0849 adenylosuccinate lyase; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily
  
 0.994
glyA
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
  
 0.994
folD
Bifunctional protein FolD; Catalyzes the oxidation of 5,10- methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10-methenyltetrahydrofolate to 10- formyltetrahydrofolate
 
 0.989
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
 
 0.989
guaB
Inosine-5'-monophosphate dehydrogenase; 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
 
 0.988
purM
Phosphoribosylformylglycinamidine cyclo-ligase; KEGG: gsu:GSU1758 phosphoribosylaminoimidazole synthetase; TIGRFAM: phosphoribosylformylglycinamidine cyclo-ligase; PFAM: AIR synthase related protein; AIR synthase related protein domain protein
 
 
 0.983
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine
 
 
 0.978
purC
KEGG: gme:Gmet_0916 SAICAR synthetase; TIGRFAM: phosphoribosylaminoimidazole-succinocarboxamide synthase; PFAM: SAICAR synthetase
  
 
 0.976
