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

AKZ50173.15'-nucleotidase; Derived by automated computational analysis using gene prediction method: Protein Homology. (670 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.
    
 0.934
guaA
GMP synthase; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 0.928
AKZ50074.1
Nuclease; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 0.927
PurA
Adenylosuccinate synthetase; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 0.923
PunA
Purine nucleoside phosphorylase; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate.
  
 
 0.922
purB
Adenylosuccinate lyase; Catalyzes two discrete reactions in the de novo synthesis of purines: the cleavage of adenylosuccinate and succinylaminoimidazole carboxamide ribotide; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 
 0.919
CinA
Damage-inducible protein CinA; Derived by automated computational analysis using gene prediction method: Protein Homology.
