Biosynthese des vollständig gesättigten C16‐Homosesquiterpens Descartan durch Deprotonierung mit Cyclopropanierung

open access: yesAngewandte Chemie, Volume 138, Issue 38, 14 September 2026.
Eine nicht‐kanonische C16‐Sesquiterpensynthase aus Morganella morganii produziert das ungewöhnliche Grundgerüst Descartan. Ihr Cyclisierungsmechanismus wurde mittels Isotopenmarkierungsexperimenten und DFT‐Berechnungen aufgeklärt. Gezielte Mutagenese veränderte die Enzymfunktion und führte zu alternativen Produkten, darunter Voltairen, dessen ...

Biosynthesis of the Fully Saturated C16 Homosesquiterpene Descartane Through Deprotonation With Cyclopropanation

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 38, 14 September 2026.
A non‐canonical C16 sesquiterpene synthase from Morganella morganii produces the unusual scaffold descartane. Its cyclisation mechanism was rationalised by isotopic labelling experiments and DFT calculations. Site‐directed mutagenesis altered enzyme function, resulting in alternative products, including voltairene, which requires a different ...
