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

purEN5-(carboxyamino)imidazole ribonucleotide mutase; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR). (163 aa)    
Predicted Functional Partners:
purK
N5-carboxyaminoimidazole ribonucleotide synthetase; Catalyzes the ATP-dependent conversion of 5-aminoimidazole ribonucleotide (AIR) and HCO(3)(-) to N5-carboxyaminoimidazole ribonucleotide (N5-CAIR).
 
 0.999
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
purD
Phosphoribosylamine glycine ligase (also known as phosphoribosylglycinamide synthetase) catalyses the second step in the de novo biosynthesis of purine: the ATP-dependent addition of 5-phosphoribosylamine to glycine to form 5'phosphoribosylglycinamide. Localized in the cytoplasm; High confidence in function and specificity; Belongs to the GARS family.
  
 0.996
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.
 
 
 0.991
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.
 
  
 0.969
purN
Phosphoribosylglycinamide formyltransferase; 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.
 
  
 0.967
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.
 
  
 0.918
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.
 
  
 0.914
purB
Adenylosuccinate 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.
  
  
 0.877
carA
Carbamoyl-phosphate synthase catalyses the ATP-dependent synthesis of carbamyl-phosphate from glutamine or ammonia and bicarbonate. This important enzyme initiates both the urea cycle and the biosynthesis of arginine and/or pyrimidines. It is a heterodimer of a small and large chain. The small chain promotes the hydrolysis of glutamine to ammonia, which is used by the large chain to synthesize carbamoyl phosphate. Binds three magnesium ion as cofactor. Localized in the cytoplasm; High confidence in function and specificity; Belongs to the CarA family.
