  对来自鲍曼不动杆菌的立体特异性和热稳定性 II 类醛缩酶 HpaI 的催化和结构洞察。

  摘要：

  醛缩酶催化醛醇缩合和裂解的可逆反应，具有很强的合成手性化合物的潜力，广泛用于药物。在这里，我们研究了鲍曼不动杆菌对羟基苯乙酸酯降解途径中的一种新的 II 类金属醛缩酶，即 4-羟基-2-酮-庚烷-1,7-二酸醛缩酶 (AbHpaI)，它具有适合生物催化的各种特性，包括立体选择性/立体特异性、广泛的醛利用、热稳定性和溶剂耐受性。值得注意的是，AbHpaI 使用 Zn2+ 作为天然辅因子与此类中的其他酶不同。AbHpaI 还可以使用除 Ca2+ 之外的其他金属离子 (M2+) 辅助因子进行催化。我们发现 Zn2+ 产生最高的酶复合物热稳定性（Tm 为 87 °C）和溶剂耐受性。所有 AbHpaI•M2+ 复合物均表现出对 (4R)-2-keto-3-deoxy-D-galactonate ((4R)-KDGal) 的优先裂解超过 (4S)-2-keto-3-deoxy-D-gluconate ((4S)
