Source-derived summary

Dammarenediol II synthase (EC 4.2.1.125, dammarenediol synthase, 2,3-oxidosqualene (20S)-dammarenediol cyclase, DDS, (S)-squalene-2,3-epoxide hydro-lyase (dammarenediol-II forming)) is an enzyme with systematic name (3S)-2,3-epoxy-2,3-dihydrosqualene hydro-lyase (dammarenediol-II forming). This enzyme catalyses the following chemical reaction

dammarenediol II

⇌

{\displaystyle \rightleftharpoons }

(3S)-2,3-epoxy-2,3-dihydrosqualene + H2O

The reaction occurs in the reverse direction.

Editorial summary

This brief starts where responsible research should: with the source description of “Dammarenediol II synthase” as class of enzymes. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current 48-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Dammarenediol, synthase and class can be independently traced.
Editorial analysis

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.

Evidence profile

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 21, 2025. The linked authority identifier is Q13394625. None of the 0 selected statements returned an explicit reference.

Critical limits

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

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
