Biosynthesis of YM-216391 Unveils a Bifunctional α-Ketoglutarate-Dependent Enzyme Catalyzes Hydroxylation and Epimerization in RiPPs
Nonheme iron/α-ketoglutarate-dependent dioxygenases (Fe/αKGDs) catalyze diverse oxidative transformations, including hydroxylation, desaturation, and ring expansion. Although these reactions are well established, Fe/αKGD-catalyzed epimerization remains rare and has not been characterized in ribosomally synthesized an...
