The Role of Cytochrome P450 AbyV in the Final Stages of Abyssomicin C Biosynthesis

Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
The cytochrome P450 enzyme AbyV catalyses a key epoxidation in the final stages of the biosynthesis of the spirotetronate antibiotic abyssomicin C. Combining structural and computational data with a 13C labelling strategy was found to be a powerful approach to interrogate the biotransformation and determine the precise function of the enzyme.
