ENZYME entry: EC 3.2.2.25
| Accepted Name |
|---|
| N-methyl nucleosidase.
|
| Alternative Name(s) |
|---|
| 7-methylxanthosine nucleosidase. |
| Methylpurine nucleosidase. |
| N-meNase. |
| N-methyl nucleoside hydrolase. |
| Reaction catalysed |
|---|
| 7-methylxanthosine + H(2)O <=> 7-methylxanthine + D-ribose |
| Comment(s) |
|---|
- 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.
