Preparative, in Vitro Biocatalysis of Triketide Lactone Chiral Building Blocks

PKS biocatalysis: The terminal module of erythromycin synthase was used for the in vitro production of chiral triketide lactones. Combining cofactor regeneration, substrate truncation, and enzymatic promiscuity afforded a scalable strategy to generate these molecules from abundant racemic and achiral precursors. The described biocatalytic platform thus facilitates the application and study of enzymes within PKS modules.
