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

guaAGMP synthase glutaminehydrolyzing EC 6352; Catalyzes the synthesis of GMP from XMP. (556 aa)    
Predicted Functional Partners:
guaB
Inosine5monophosphate dehydrogenase EC 111205 CBS domain; 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.
 
 0.999
gmk
Guanylate kinase EC 2748; Essential for recycling GMP and indirectly, cGMP.
 
 
 0.997
apt
Adenine phosphoribosyltransferase EC 2427; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 0.988
gpt
Xanthineguanine phosphoribosyltransferase EC 24222; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily.
  
 0.988
gatB
Aspartyl/glutamyl-tRNA(Asn/Gln) amidotransferase subunit B; Allows the formation of correctly charged Asn-tRNA(Asn) or Gln-tRNA(Gln) through the transamidation of misacylated Asp-tRNA(Asn) or Glu-tRNA(Gln) in organisms which lack either or both of asparaginyl- tRNA or glutaminyl-tRNA synthetases. The reaction takes place in the presence of glutamine and ATP through an activated phospho-Asp- tRNA(Asn) or phospho-Glu-tRNA(Gln); Belongs to the GatB/GatE family. GatB subfamily.
  
 
 0.988
BF49_0169
Nucleoside 5triphosphatase RdgB dHAPTP dITP XTPspecific EC 36115; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family.
 
 
 0.978
BF49_3171
Glutamate synthase NADPH large chain EC 14113.
  
 
 0.978
purA
Adenylosuccinate synthetase EC 6344; 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.
 
  
 0.956
BF49_0297
GMP synthase glutaminehydrolyzing EC 6352.
    
 0.948
BF49_5667
DglyceroDmannoheptose 1phosphate guanosyltransferase.
  
 
 0.946
