ENZYME entry: EC

Accepted Name
N-methyl nucleosidase.
Alternative Name(s)
7-methylxanthosine nucleosidase.
Methylpurine nucleosidase.
N-methyl nucleoside hydrolase.
Reaction catalysed
7-methylxanthosine + H(2)O <=> 7-methylxanthine + D-ribose
  • Preferentially hydrolyzes 3- and 7-methylpurine nucleosides, such as 3-methylxanthosine, 3-methyladenosine and 7-methylguanosine.
  • Hydrolysis of 7-methylxanthosine to form 7-methylxanthine is the second step in the caffeine biosynthesis pathway.
