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, glutamine amidotransferase domain (guaA); Catalyzes the synthesis of GMP from XMP. (188 aa)    
Predicted Functional Partners:
guaA-2
GMP synthase, PP-ATPase domain (guaA); Catalyzes the synthesis of GMP from XMP.

SSO0432
HAM1 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.

trpE
Anthranilate synthase component I (trpE); Part of a heterotetrameric complex that catalyzes the two- step biosynthesis of anthranilate, an intermediate in the biosynthesis of L-tryptophan. In the first step, the glutamine-binding beta subunit (TrpG) of anthranilate synthase (AS) provides the glutamine amidotransferase activity which generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by the large alpha subunit of AS (TrpE) to produce anthranilate. In the absence of TrpG, TrpE can synthesize anthranilate directly from chorismate and high c [...]
    
 0.881
purA
Adenylosuccinate synthase (IMP--aspartate ligase) (purA); 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.
 
  
 0.821
map
Methionine aminopeptidase 2; Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val); Belongs to the peptidase M24A family. Methionine aminopeptidase archaeal type 2 subfamily.
  
    0.805
purB
Adenylosuccinate lyase (adenylosuccinase)(ASL) (purB); Purines; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
 
  
 0.775
argS
Arginyl-tRNA synthetase (argS); Translation, Aminoacyl tRNA synthetases; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.772
rpl11AB
LSU ribosomal protein L11AB (rpl11AB); Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors; Belongs to the universal ribosomal protein uL11 family.
  
    0.734
purD
Phosphoribosylamine--glycine ligase (GAR synthetase) (GARS) (purD); Purines; Belongs to the GARS family.
 
  
 0.689
pyrH
Uridylate kinase (pyrH); Catalyzes the reversible phosphorylation of UMP to UDP, with ATP as the most efficient phosphate donor. Is also able to phosphorylate dUMP, although much less efficiently.
