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 nucleoside + H(2)O <=> D-ribose + a purine base
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.
