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.

guaAGMP synthase; Catalyzes the synthesis of GMP from XMP. (528 aa)    
Predicted Functional Partners:
guaB
IMP dehydrogenase related 2.
 
 
 0.982
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
 
 
 0.971
argS
arginyl-tRNA synthetase.
   
  
 0.968
surE
Stationary-phase survival protein SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.964
pyrG
CTP synthase; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates.
  
 
 0.962
AHF62635.1
Ham1-like 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.
 
 
 0.959
tufA
Elongation factor Tu; This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis.
   
  
 0.953
lysS
lysyl-tRNA synthetase; Belongs to the class-II aminoacyl-tRNA synthetase family.
  
  
 0.952
rplK
Ribosomal protein L11; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors.
   
    0.949
valS
valyl-tRNA synthetase; Catalyzes the attachment of valine to tRNA(Val). As ValRS can inadvertently accommodate and process structurally similar amino acids such as threonine, to avoid such errors, it has a 'posttransfer' editing activity that hydrolyzes mischarged Thr-tRNA(Val) in a tRNA- dependent manner; Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 1 subfamily.
