| Ec Number: | 3.2.2.25 |
In enzymology, a N-methyl nucleosidase is an enzyme that catalyzes the chemical reaction
7-methylxanthosine + H2O
\rightleftharpoons
Thus, the two substrates of this enzyme are 7-methylxanthosine and H2O, whereas its two products are 7-methylxanthine and D-ribose.
This enzyme belongs to the family of hydrolases, specifically those glycosylases that hydrolyse N-glycosyl compounds. The systematic name of this enzyme class is 7-methylxanthosine ribohydrolase. Other names in common use include 7-methylxanthosine nucleosidase, N-MeNase, N-methyl nucleoside hydrolase, and methylpurine nucleosidase.
