Evolutionäre, funktionelle und mechanistische Charakterisierung mikrobieller Terpensynthase‐ähnlicher Gene aus Springschwänzen

Angewandte Chemie, EarlyView.
Eine Genomanalyse zeigte das Vorkommen zahlreicher Terpensynthasen des bakteriellen Typs in Springschwänzen. Vier Enzyme aus Sinella curviseta wurden funktionell charakterisiert, was zur Isolierung mehrerer Verbindungen führte, darunter Sinellenether, der erste identifizierte Diterpenether einer Terpensynthase mit einem neuartigen Grundgerüst.
