We report the identification of the biosynthetic cluster from the marine-derived fungus and the in vivo characterization of a cryptic type I diterpene synthase. The heterologous expression of the bifunctional terpene synthase led to the discovery of a diterpene backbone, talarodiene, harboring a benzo[]cyclopenta[]cyclooctane tricyclic fused ring system. The conversion of geranylgeranyl diphosphate to talarodiene was investigated using C-labeling studies, and stable isotope tracer experiments showed the biotransformation of talarodiene into talaronoid C.
我们报告了海洋来源真菌的生物合成簇的鉴定和一种隐型 I 型二萜合酶的体内表征。异源表达双功能萜烯合酶导致发现了一种具有苯并[]环戊[]环辛烷三环融合环系统的二萜骨干化合物 talarodiene。使用 C 标记研究调查了香叶基香叶基二磷酸向 talarodiene 的转化,稳定同位素示踪实验表明 talarodiene 向 talaronoid C 的生物转化。
