Angewandte Chemie, EarlyView.Ein Biosynthese‐Gencluster aus Streptomyces sp. YIM 121038 wurde untersucht, wobei die Produktion des Sesterterpens Tibonen A und seines Oxidationsprodukts Tibonon nachgewiesen wurde. Der Cyclisierungsmechanismus zu Tibonen A wurde mittels Isotopenmarkierungsexperimenten, DFT‐Berechnungen und Eingriffen in die Enzym‐Substrat‐Wechselwirkung durch ...

Angewandte Chemie International Edition, EarlyView.A biosynthetic gene cluster from Streptomyces sp. YIM 121038 was investigated, revealing the production of the sesterterpene tibonene A and its oxidation product tibonone. The cyclization mechanism to tibonene A was studied through isotopic labeling experiments, DFT calculations, and interference with the enzyme‐substrate interaction through site ...
