Engineering of an Fe2+/α-Ketoglutarate-Dependent Dioxygenase Enables Stereoselective and Efficient Sulfoxide Synthesis
Alliin (S-allyl-l-cysteine sulfoxide) is a valuable bioactive sulfur compound and an allicin precursor. However, its biocatalytic synthesis is limited by poor stereocontrol of an Fe2+/α-ketoglutarate-dependent dioxygenase (l-isoleucine dioxygenase, IDO) that converts S-allyl-l-cysteine (SAC) into alliin. Herein, we a...
