synthase (StTrpS) catalyses the condensation of 2‐, 4‐, 6‐ and 7‐substituted indoles with threonine to give (2S,3S)‐β‐methyltryptophans (β‐mTrp), which are important building blocks in drug synthesis. Addition of l‐amino acid oxidase (LAAO) gives (2R,3S)‐β‐mTrp. Halogenase (Hal) enzymes also provide halogenated β‐mTrp derivatives that can be arylated in a one‐pot chemo‐biotransformation.
