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.

Score
guaA1GMP synthase (glutamine-hydrolysing); Catalyzes the synthesis of GMP from XMP. (524 aa)    
Predicted Functional Partners:
guaB1
IMP dehydrogenase; Family membership.
 0.998
guaB2
IMP dehydrogenase; Family membership.
 0.998
yggV
Putative ribosomal protein; 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.
 
 
 0.965
purL
Phosphoribosylformylglycinamidine synthase,probable; 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.
  
  
 0.964
gmk
Putative Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
 
 
 0.964
hpt
Hypoxanthine-phosphoribosyltransferase; Family membership; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.952
surE1
Acid phosphatase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.948
purH
IMP cyclohydrolase; Family membership.
 
  
 0.946
argS
Arginine--tRNA ligase; High confidence in function and specificity.
  
  
 0.944
sce2818
Putative Nucleoside-triphosphatase; Family membership.
  
 
 0.943
