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.
