Vibralactone is a strong lipase inhibitor and a bicyclic β-lactone containing an oxepinone ring, whose biosynthetic construction was unknown. Here the authors identify an oxepinone-building flavin monooxygenase VibO that is involved in the biosynthesis of vibralactone, and determine its X-ray crystal structure.
