Baeyer-Villiger单加氧酶(BVMO)作为一种重要的生物催化剂,可以催化各种有机酮/醛化合物的Baeyer-Villiger氧化反应,以及一些含硫、硒、硼等杂原子底物的氧化反应.Baeyer-Villiger单加氧酶催化的氧化反应具有选择性高、反应条件温和、高效等优点,已成为不可或缺的有机合成工具,被广泛应用于各种手性化合物的合成中.近年来利用生物信息学分析和基因挖掘技术,从众多微生物中找到了多种新型的BVMO·另外利用蛋白质工程技术对已知的野生型BVMO进行改造,从而扩大底物范围,提高热稳定性和反应活性,改善酶的立体、区域和化学选择性.这些都进一步扩大了Baeyer-Villiger单加氧酶催化氧化反应的应用范围.以不同底物结构的Baeyer Villiger氧化反应为主线,综述了近5年来国内外对野生型以及蛋白质工程改造的BVMO催化氧化反应研究的新进展.

Baeyer-Villiger monooxygenase (BVMO) is an important biocatalyst for Baeyer-Villiger oxidation of various organic ketone/aldehyde compounds, and sulfur, selenium, or boron-containing heteroatoms compounds. As an indispensable tool, BVMO-catalyzed oxidation displays some advantages, such as high selectivity, mild reaction conditions and high efficiency, leading to wide applications into the synthesis of chiral compounds. In recent years, bioinformatics analysis and genome mining have been used to find more novel BVMOs from microorganisms. Besides natural substrates, these BVMOs can accept various organic compounds showing wide substrate scope. Meanwhile, protein engineering has been widely used to improve the catalytic performance of BVMOs, such as the expanded substrate scope, high thermostability and activity, high stereo-, regio-and chemo-selectivities. Based on the Baeyer-Villiger oxidation reaction with different substrate structures, the recent advancements in the research on the catalytic oxidation of wild type and protein-engineered BVMOs in the past five years are summarized.
