N-methyl nucleosidase
class of enzymes
N-methyl nucleosidase (EC 3.2.2.25) is an enzyme that catalyzes the chemical reaction
This hydrolysis reaction is the second step in the biosynthesis of caffeine from the nucleoside, xanthosine. 7-Methylxanthine is subsequently methylated by the enzyme theobromine synthase.
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.
This brief starts where responsible research should: with the source description of “N-methyl nucleosidase” as class of enzymes. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as class of enzymes. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 5, 2026. The linked authority identifier is Q6951492. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
