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

purPPredicted 5-formaminoimidazole-4-carboxamide-1-(beta)-D- ribofuranosyl 5'- monophosphate synthetase; Catalyzes the ATP- and formate-dependent formylation of 5- aminoimidazole-4-carboxamide-1-beta-d-ribofuranosyl 5'-monophosphate (AICAR) to 5-formaminoimidazole-4-carboxamide-1-beta-d-ribofuranosyl 5'-monophosphate (FAICAR) in the absence of folates. (363 aa)    
Predicted Functional Partners:
purO
IMP cyclohydrolase; Catalyzes the cyclization of 5-formylamidoimidazole-4- carboxamide ribonucleotide to IMP.
 
  
 0.956
purB
Adenylosuccinate lyase; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
 
  
 0.950
apt
Predicted adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of IMP that is energically less costly than de novo synthesis. Prefers hypoxanthine, has 66% activity with guanine while activity with adenine, xanthine, uracil, orotate, or cytosine is negligible.
    
  0.903
hisF
Imidazoleglycerol-phosphate synthase, subunit HisF; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit.
 
  
  0.834
hisH
Predicted imidazole glycerol phosphate synthase, subunit H; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisH subunit catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the synthesis of IGP and AICAR. The resulting ammonia molecule is channeled to the active site of HisF.
    
  0.806
ADL58423.1
Conserved hypothetical protein; Belongs to the UPF0201 family.
  
   
 0.619
taw2
Predicted methyltransferase; S-adenosyl-L-methionine-dependent transferase that acts as a component of the wyosine derivatives biosynthesis pathway. Catalyzes the transfer of the alpha-amino-alpha-carboxypropyl (acp) group from S- adenosyl-L-methionine to 4-demethylwyosine (imG-14), forming 7- aminocarboxypropyl-demethylwyosine (wybutosine-86) at position 37 of tRNA(Phe).
 
     0.605
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.
     
 0.577
purM
Phosphoribosylformylglycinamidine cyclo-ligase.
     
 0.550
ADL59156.1
Conserved hypothetical protein.
       0.543
