ENZYME entry: EC 3.2.2.1

Accepted Name
purine nucleosidase.
Alternative Name(s)
IAG-NH.
IAG-nucleoside hydrolase.
inosine-adenosine-guanosine preferring nucleoside hydrolase.
N-D-ribosylpurine ribohydrolase.
N-ribosyl purine ribohydrolase.
nucleosidase.
nucleosidase g.
nucleoside hydrolase.
purine beta-ribosidase.
purine nucleoside hydrolase.
purine ribonucleosidase.
purine-specific nucleoside N-ribohydrolase.
ribonucleoside hydrolase.
Reaction catalysed
a purine D-ribonucleoside + H2O <=> a purine nucleobase + D-ribose
Comment(s)
  • The enzyme from the bacterium Ochrobactrum anthropi specifically catalyzes the irreversible N-riboside hydrolysis of purine nucleosides.
  • Pyrimidine nucleosides, purine and pyrimidine nucleotides, NAD(+), NADP(+) and nicotinaminde mononucleotide are not substrates.
