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, large subunit; Catalyzes the synthesis of GMP from XMP. (308 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 (glutamine-hydrolyzing) subunit A; Catalyzes the synthesis of GMP from XMP.
  
 0.999
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.
  
 0.983
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.
  
 
 0.965
ADZ08355.1
Non-canonical purine NTP pyrophosphatase, rdgB/HAM1 family; 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.
 
 
 0.955
surE
Multifunctional protein surE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.945
argS
KEGG: mth:MTH1447 arginyl-tRNA synthetase; TIGRFAM: Arginyl-tRNA synthetase, class Ic; HAMAP: Arginyl-tRNA synthetase, class Ic; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.925
ADZ10737.1
PfkB domain protein; PFAM: Carbohydrate/purine kinase; KEGG: mth:MTH1544 ribokinase; Belongs to the carbohydrate kinase PfkB family.
  
 
 0.925
ADZ09420.1
KEGG: mst:Msp_0490 putative asparagine synthetase; TIGRFAM: Asparagine synthase, glutamine-hydrolyzing; PFAM: Asparagine synthase; Glutamine amidotransferase, class-II.
  
  
 0.889
truB
tRNA pseudouridine synthase B; Could be responsible for synthesis of pseudouridine from uracil-55 in the psi GC loop of transfer RNAs; Belongs to the pseudouridine synthase TruB family. Type 2 subfamily.
  
  
 0.862
