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

purBAdenylosuccinate lyase catalyzes step 8 in the pathway for de novo synthesis of IMP and also the final reaction in the two-step sequence from IMP to AMP. It cleaves succinylaminoimidazole carboxamide ribotide into aminoimidazole carboxamide ribotide and fumarate, as well as adenylosuccinate into adenylate and fumarate. Localized in the cytoplasm; High confidence in function and specificity. (447 aa)    
Predicted Functional Partners:
purL
Phosphoribosylformylglycinamidine synthase; 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
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.
 0.997
purC
Phosphoribosylaminoimidazole-succinocarboxamide synthase catalyzes the seventh step in the de novo purine biosynthetic pathway: the ATP-dependent conversion of 5'-phosphoribosyl-5-aminoimidazole-4-carboxylic acid and aspartic acid to SAICAR. It forms a homotrimer. Localized in the cytoplasm; High confidence in function and specificity.
 
 0.992
purH
Bifunctional enzyme that catalyses the last two steps in de novo purine biosynthesis. The second last step is catalysed by 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR) formyltransferase that catalyses the formylation of AICAR with 10-formyl-tetrahydrofolate to yield 5-formylaminoimidazole-4-carboxamide ribonucleotide (FAICAR) and tetrahydrofolate. The last step is catalysed by IMP (Inosine monophosphate) cyclohydrolase, cyclizing FAICAR to IMP; Belongs to the purH family; Localized in the cytoplasm; High confidence in function and specificity.
  
 0.990
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 0.958
hptA/adkA
Bifunctional protein Hypoxanthine-guanine phosphoribosyltransferase / Adenylate kinase; Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. Plays an important role in cellular energy homeostasis and in adenine nucleotide metabolism; Belongs to the adenylate kinase family.
  
 0.953
purF
Amidophosphoribosyltransferase catalyzes the first step in purine biosynthesis: 5-phospho-beta-D-ribosylamine + diphosphate + L-glutamate = L-glutamine + 5-phospho-alpha-D-ribose 1-diphosphate + H2O. PurF belongs to the Class-II glutamine amidotransferase family. It forms a homotetramer and binds one magnesium ion per subunit. Localized in the cytoplasm; High confidence in function and specificity.
 
 
 0.941
surE
Stationary-phase survival protein surE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.922
argH
Argininosuccinate lyase is involved in the eighth and last step of the arginine biosynthesis pathway. It converts the Omega-N-(L-arginino)succinate to fumarate and L-arginine; Belongs to the fumarate lyase family. Localized in the cytoplasm; High confidence in function and specificity.
    
 0.920
purM
Phosphoribosylformylglycinamidine cyclo-ligase is involved in purine biosynthesis. It catalyzes the reaction: ATP + 2-(formamido)-N1-(5-phospho-D- ribosyl)acetamidine = ADP + phosphate + 5-amino-1-(5-phospho-D-ribosyl)imidazole. Localized in the cytoplasm; High confidence in function and specificity.
