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

guaAAGMP synthetase, subunit A; Catalyzes the synthesis of GMP from XMP. (186 aa)    
Predicted Functional Partners:
guaAB
GMP synthetase, subunit B; Catalyzes the synthesis of GMP from XMP.
  
 0.999
guaB
Inosine-5'-monophosphate dehydrogenase; 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.
 
 
 0.994
hpt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of IMP that is energically less costly than de novo synthesis. Belongs to the purine/pyrimidine phosphoribosyltransferase family. Archaeal HPRT subfamily.
  
 
 0.977
MTH_1424
Conserved 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.
 
 
 0.953
surE
Survival protein SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.951
MTH_1544
Ribokinase; Catalyzes the phosphorylation of a wide range of nucleosides to yield nucleoside monophosphates, using ATP, ITP or GTP as phosphate donor.
  
 
 0.920
trpD
Anthranilate phosphoribosyltransferase; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA).
    
 0.902
purA
Adenylosuccinate synthetase; 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.
 
  
 0.888
rpl13/rps9
Ribosomal protein S16 (E.coli); L13 protein is one of the early assembly proteins of the 50S ribosomal subunit, although it is not seen to bind rRNA by itself. It is important during the early stages of 50S assembly (By similarity).
  
  
 0.861
purB
Adenylosuccinate lyase; Function Code:4.01 - Nucleotide Metabolism, Purine metabolism; similar to, pir:LN:A64416 AC:A64416, p()=1.2E-149, pid=59%.
 
  
 0.836
