Complementary P450 radical cyclases are obtained allowing access to both enantiomeric products.

• Selected as the cover story of the Journal of the American Chemical Society
About the Cover: A combined computational and experimental study reveals that, contrary to previously hypothesized enantioinduction mechanisms, the radical rebound step is enantioselectivity-determining under the Curtin–Hammett conditions, whereas the preceding HAT step is only moderately stereoselective. This study highlights an unusual enantioinduction mechanism in metalloenzyme-catalyzed asymmetric transformations involving radical intermediates. Cover art by Binh Khanh Mai.
