substrate-to-catalyst ratio (Msubstrate/Mcatalyst: 25 000), enzymatic stability (one month without any activity loss), and excellent protein purification yields (130 mg from 2 g of wet cell paste) made this process a green and cost-efficient approach, which was successfully applied for the preparation of a key intermediate of SAHA synthesis.
开发了一种基于使用耻垢分枝杆菌(MsAcT) 的酰基转移酶在水中制备氨基含氧酸的高效策略。从苯胺和一系列不同的酸酐开始,以优异的产率 (68–94%) 和快速反应 (0.5–5 h) 进行了 1 M 规模的生物转化。高底物催化剂比(M底物/ M催化剂:25 000)、酶稳定性(一个月没有任何活性损失)和出色的蛋白质纯化产量(从 2 克湿细胞糊中提取 130 毫克)使该工艺成为绿色、经济高效的方法,成功应用于制备SAHA合成的关键中间体。
