Biochemical Characterization of a Eukaryotic Decalin-Forming Diels-Alderase

J Am Chem Soc. 2016 Dec 14;138(49):15837-15840. doi: 10.1021/jacs.6b10452. Epub 2016 Nov 30.

Abstract

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.
