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

purPConserved protein; 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. Belongs to the phosphohexose mutase family. (377 aa)    
Predicted Functional Partners:
purB
Adenylosuccinate lyase; Function Code:4.01 - Nucleotide Metabolism, Purine metabolism; similar to, pir:LN:A64416 AC:A64416, p()=1.2E-149, pid=59%.
 
  
 0.970
purO
Conserved protein; Catalyzes the cyclization of 5-formylamidoimidazole-4- carboxamide ribonucleotide to IMP.
    
 0.965
hpt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of IMP that is energically less costly than de novo synthesis. Belongs to the purine/pyrimidine phosphoribosyltransferase family. Archaeal HPRT subfamily.
    
  0.902
hisF
Imidazoleglycerol-phosphate synthase (cyclase); 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 (By similarity).
    
  0.805
hisH
Imidazoleglycerol-phosphate synthase; 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 (By similarity).
    
  0.805
purL
Phosphoribosylformylglycinamidine synthase II; 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 [...]
     
 0.791
purM
Phosphoribosylformylglycinamidine cyclo-ligase; Function Code:4.01 - Nucleotide Metabolism, Purine metabolism; similar to, sp:LN:PUR5_METJA AC:Q57656, p()=2.6E-81, pid=47%.
 
   
 0.789
purE
Phosphoribosylaminoimidazole carboxylase; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
     
 0.703
purD
Glycinamide ribonucleotide synthetase; Function Code:4.01 - Nucleotide Metabolism, Purine metabolism; similar to, pir:LN:A64417 AC:A64417, p()=9E-120, pid=53%.
     
 0.664
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
