Oxidase‐catalyzed kinetic resolution is important for the production of enantiopure 2‐hydroxycarboxylic acids (2‐HAs), which are versatile building blocks for the synthesis of many significant compounds. However, in contrast to that of (R)‐2‐HAs, the production of (S)‐2‐HA is challenging because of the lack of related oxidases. Herein, suitable enzymes were screened systematically through the analysis
氧化酶催化的动力学拆分对于生产对映体纯的2-羟基羧酸(2-HAs)非常重要,这是合成许多重要化合物的通用构建基块。但是,与(R)-2-HAs相比,由于缺乏相关的氧化酶,(S)-2-HA的生产具有挑战性。在这里,通过分析许多推定的d-乳酸氧化酶序列并鉴定一些所需的特性,系统地筛选了合适的酶。最后,选择氧化葡糖杆菌621H中的d-乳酸氧化酶,具有良好的溶解度,底物谱宽,立体选择性高等优点,可将2-HAs分解为(S)-2-HAs。使用该d-乳酸氧化酶成功生产了多种(S)-2-HAs,其对映体过量值极佳(> 99%)。提出的目标生物催化筛选标准和方法为生产旋光活性化学物质(S)-2-HAs提供了指导原则。
