The trans-decalin structure formed by intramolecular Diels-Alder cycloaddition is widely present among bioactive natural products isolated from fungi. We elucidated the concise three-enzyme biosynthetic pathway of the cytotoxic myceliothermophin and biochemically characterized the Diels-Alderase that catalyzes the formation of trans-decalin from an acyclic substrate. Computational studies of the reaction mechanism rationalize both the substrate and stereoselectivity of the enzyme.
