Ent-isokaurene synthase
class of enzymes

ent-Isokaurene synthase (EC 4.2.3.103, OsKSL5i, OsKSL6) is an enzyme with systematic name ent-copalyl-diphosphate diphosphate-lyase (cyclizing, ent-isokaurene-forming). This enzyme catalyses the following chemical reaction
ent-copalyl diphosphate
⇌
{\displaystyle \rightleftharpoons }
ent-isokaurene + diphosphate
Two enzymes of the rice sub-species Oryza sativa ssp. indica, OsKSL5 and OsKSL6, produce ent-isokaurene.
Begin with the source’s own compact description: “Ent-isokaurene synthase” is class of enzymes. The dossier treats that line as a proposition to test through Ent-isokaurene, synthase and class, not as a finished interpretation.
Why this record matters
The phrase “class of enzymes” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 Aug 26, 2023. The linked authority identifier is Q13405263. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
