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.
它变得对我:一个突变体色氨酸合酶(圣的TRP)催化的2-,4-缩合,6-和7-取代的吲哚与苏氨酸,得到(2 S, 3小号)-β-methyltryptophans(β-MTRP) ,它们是药物合成中的重要组成部分。加入l-氨基酸氧化酶(LAAO)得到(2 R,3 S)-β-mTrp。卤化酶(Hal)酶还提供卤化的β-mTrp衍生物,可以在一锅化学生物转化中被芳基化。
