believed to be a crucial step in fungal seco-anthraquinone biosynthesis and has long been proposed as a classic Baeyer–Villiger oxidation. Nonetheless, genetic, enzymatic, and chemical information on ringopening remains elusive. Here, a revised questin ring-opening mechanism was elucidated by in vivo gene disruption, in vitro enzymatic analysis, and 18O chasing experiments. It has been confirmed that the
