7-deoxyloganin 7-hydroxylase
class of enzymes
In enzymology, a 7-deoxyloganin 7-hydroxylase (EC 1.14.13.74) is an enzyme that catalyzes the chemical reaction
7-deoxyloganin + NADPH + H+ + O2
⇌
{\displaystyle \rightleftharpoons }
loganin + NADP+ + H2O
The 4 substrates of this enzyme are 7-deoxyloganin, NADPH, H+, and O2, whereas its 3 products are loganin, NADP+, and H2O.
This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with NADH or NADPH as one donor, and incorporation of one atom o oxygen into the other donor. The systematic name of this enzyme class is 7-deoxyloganin,NADPH:oxygen oxidoreductase (7alpha-hydroxylating). This enzyme participates in indole and ipecac alkaloid biosynthesis.

This brief starts where responsible research should: with the source description of “7-deoxyloganin 7-hydroxylase” 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.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 30, 2025. The linked authority identifier is Q3599684. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2001 and 1016.
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.
