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

PurHAICAR transformylase/IMP cyclohydrolase PurH (only IMP cyclohydrolase domain in Aful); Best Blastp hit = gi|10173247|dbj|BAB04352.1| (AP001509) phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase [Bacillus halodurans], score 611, E-value 1.00E-174. (508 aa)    
Predicted Functional Partners:
PurN
Folate-dependent phosphoribosylglycinamide formyltransferase PurN; 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
Phosphoribosylaminoimidazol (AIR) synthetase; Best Blastp hit = gi|11272453|pir||E81104 phosphoribosylformylglycinamidine cyclo-ligase NMB1252 [imported] - Neisseria meningitidis (group B strain MD58) gi|7226492|gb|AAF41632.1| (AE002473) phosphoribosylformylglycinamidine cyclo-ligase [Neisseria meningitidis MC58], score 375, E-value 1.00E-103.
 
  
 0.997
PurD
Phosphoribosylamine-glycine ligase; Best Blastp hit = gi|10173248|dbj|BAB04353.1| (AP001509) phosphoribosylglycinamide synthetase [Bacillus halodurans], score 408, E-value 1.00E-113.
 
 
 0.997
PurB
Adenylosuccinate lyase; Best Blastp hit = gi|3983439|gb|AAC83935.1| (AF106656) adenylosuccinate lyase [Homo sapiens], score 469, E-value 1.00E-131; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
  
 0.995
GlyA
Glycine 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.
  
 0.995
GuaB
IMP dehydrogenase/GMP reductase; 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.
  
 
 0.992
PurF
Glutamine phosphoribosylpyrophosphate amidotransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
 
 
 0.988
MIS1
Formyltetrahydrofolate synthetase; Best Blastp hit = gi|120563|sp|P21164|FTHS_MOOTH FORMATE--TETRAHYDROFOLATE LIGASE (FORMYLTETRAHYDROFOLATE SYNTHETASE) (FHS) (FTHFS) gi|98640|pir||A35942 formate--tetrahydrofolate ligase (EC 6.3.4.3) - Clostridium thermaceticum gi|144816|gb|AAA23240.1| (J02911) formyltetrahydrofolate synthetase (FTHFS) (ttg start codon) (EC 6.3.4.3) [Moorella thermoacetica], score 744, E-value 0.
  
 0.986
PurA
Adenylosuccinate synthase; 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.
  
 0.984
PurE
Phosphoribosylcarboxyaminoimidazole (NCAIR) mutase; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR).
