This review summarizes all aspects of mandelate racemase relevant for the application of this enzyme in preparative-scale biotransformations with special emphasis on its substrate tolerance. Collection and evaluation of substrate structure-activity data led to a set of general guidelines, which were used as basis for the construction of a general substrate model, which allows a quick estimation of the
扁桃消旋酶(EC 5.1.2.2)是少数几个生化特性良好的消旋酶之一。这种不依赖辅因子的酶的出色稳定性及其广泛的底物耐受性使其成为非天然α-羟基羧酸在生理反应条件下外消旋化的理想候选者,该条件可用于脱硫方案中,并与动力学拆分步骤结合使用。这篇综述总结了与该酶在制备规模生物转化中的应用有关的扁桃酸酯消旋酶的所有方面,并特别强调了其底物耐受性。底物结构活性数据的收集和评估导致了一套通用准则,这些准则被用作构建通用底物模型的基础,该准则可以快速估算给定底物的预期活性。
