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

guaABGMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP. (305 aa)    
Predicted Functional Partners:
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.
 
 0.999
guaAA
GMP synthase, small subunit; Catalyzes the synthesis of GMP from XMP.
  
 0.998
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.
 
 
 0.998
hpt
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.
  
 0.992
surE
3'-nucleotidase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.964
ABN58171.1
dITPase; 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.
 
 
 0.960
ABN56792.1
Cytidine kinase / inosine-guanosine kinase; PFAM: PfkB domain protein; KEGG: mhu:Mhun_0077 PfkB; Belongs to the carbohydrate kinase PfkB family.
  
 
 0.937
argS
KEGG: mhu:Mhun_2837 arginyl-tRNA synthetase; TIGRFAM: arginyl-tRNA synthetase; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.930
ABN57078.1
PFAM: metallophosphoesterase; 5'-Nucleotidase domain protein; KEGG: mhu:Mhun_2724 5'-nucleotidase-like.
    
 0.915
ABN57827.1
TIGRFAM: acetylornithine and succinylornithine aminotransferases; PFAM: aminotransferase class-III; KEGG: mhu:Mhun_2526 acetylornithine and succinylornithine aminotransferases; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
