  生菜 (Lactuca sativa L.) 苯丙氨酸氨裂解酶作为生产 d-和 l-氨基酸的稳健生物催化剂的表征

  摘要：

  苯丙氨酸解氨酶 (PAL) 催化L-苯丙氨酸可逆转化为相应的反式肉桂酸，从而提供了一条获得光学纯 α-氨基酸的途径。我们探索了生菜（ Lactuca sativa L.）基因组中编码的所有五种 PAL 的催化功能，此前已知这些 PAL 与伤口褐变有关。所有Ls PAL 在氨消除反应中均对L-苯丙氨酸具有活性，并在 55–60 °C 和 pH 9.0–9.5 时表现出最大活性。然而，其中的四种（ Ls PAL1– Ls PAL4）表现出比Ls PAL5 显着更高的活性和热稳定性，以及更广泛的底物谱，包括一些具有空间要求或给电子取代基的具有挑战性的底物。对最好的Ls PAL3 进行了一组 21 种外消旋苯丙氨酸衍生物的动力学拆分，以及 21 种肉桂酸衍生物的氨加成。它在大多数情况下表现出优异的对映选择性，并且对于许多具有挑战性的非天然底物，其活性明显优于之前描述的 PAL，这证明了其在生物催化方面的巨大潜力。

  With a dual organocatalytic system involving a chiral phosphoric acid and a dicyanopyrazine-derived chromophore (DPZ) photosensitizer and under the irradiation with visible light, an enantioselective Minisci-type addition of α-amino acid-derived redox-active esters (RAEs) to isoquinolines has been developed. A variety of prochiral α-aminoalkyl radicals generated from RAEs were successfully introduced
