P450 Enzyme LyoI Performs Hydro‐2,2′‐Bifuran Oxidation in the Polyether Ionophore Lysocellin

Angewandte Chemie, EarlyView.
In a study of the biosynthesis of the polyether ionophore lysocellin, the P450 enzyme LyoI was found to catalyze a rare oxidation of a hydro‐2,2′‐bifuran moiety to its hemiketal form. The oxidation was identified as the key for unlocking the bioactivity of lysocellin.
