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

purHPhosphoribosylaminoimidazolecarboxamide formyltransferase; Bifunctional; bifunctional purine biosynthesis protein PURH. (SW:PUR9_SALTY); IMP cyclohydrolase. (529 aa)    
Predicted Functional Partners:
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).
 
  
 0.999
purB
Similar to E. coli adenylosuccinate lyase (AAC74215.1); Blastp hit to AAC74215.1 (456 aa), 94% identity in aa 1 - 456.
  
 0.999
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine; In the C-terminal section; belongs to the purine/pyrimidine phosphoribosyltransferase family.
 
 
 0.999
purM
AIR synthetase; similar to E. coli phosphoribosylaminoimidazole synthetase = AIR synthetase (AAC75552.1); Blastp hit to AAC75552.1 (345 aa), 91% identity in aa 1 - 345.
 
  
 0.999
purN
Polyphosphate kinase; 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
purG
Phosphoribosylformylglycinamidine 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
GAR synthetase; phosphoribosylamine--glycine ligase. (SW:PUR2_SALTY); Belongs to the GARS family.
 
 
 0.999
purE
Phosphoribosylaminoimidazole carboxylase = AIR carboxylase, catalytic subunit; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
 
  
 0.998
purC
SAICAR synthetase; similar to E. coli phosphoribosylaminoimidazole-succinocarboxamide synthetase = SAICAR synthetase (AAC75529.1); Blastp hit to AAC75529.1 (237 aa), 94% identity in aa 1 - 237.
 
 
 0.997
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 (By similarity).
