of the most common biosynthetic strategies to form diaryl ethers. In contrast, enzymatic diaryl ether generation that proceeds in a nonoxidative manner has not been characterized thus far. Here, we discovered a versatile thioesterase (TE) domain from the nonreducing polyketide synthase (nrPKS) AN7909, which catalyzes diaryl ether formation through a series of successive steps involving esterification
氧化偶联和氧化重排是形成二芳基醚的两种最常见的生物合成策略。相比之下,迄今为止尚未表征以非氧化方式进行的酶促二芳基醚生成。在这里,我们从非还原性聚酮化合物合酶 (nrPKS) AN7909 中发现了一个多功能硫酯酶 (TE) 结构域,该结构域通过一系列涉及酯化、Smiles 重排和水解的连续步骤催化二芳基醚的形成。使用合成模拟底物进行的进一步突变和生化分析提供了对提议的 TE 域催化过程的深入了解。
