Baeyer-Villiger monooxygenases in the biosynthesis of microbial secondary metabolites

拜耳-维立格单加氧酶是一类可以催化酮生成酯以及硫等杂原子氧化的黄素依赖的单加氧酶,在合成化学和生物催化等工业领域有重要的应用前景。本文总结了微生物次生代谢产物生物合成途径中涉及的拜耳-维立格反应,讨论了其反应的特点和催化这些反应的拜耳-维立格单加氧酶的氨基酸序列特征,为拜耳-维立格单加氧酶的蛋白质工程改造提供参考。

Baeyer-Villiger monooxygenases, a well-studied class of flavin-dependent enzymes, catalyze the conversion of ketones to lactones or esters and the oxygenation of heteroatoms, which possesses great practical prospect in synthetic chemistry and biocatalysis. In this review, we focus on Baeyer-Villiger oxidations involved in biosynthesis of microbial secondary metabolites and discuss the characteristics of these Baeyer-Villiger oxidations and Baeyer-Villiger monooxygenases, to provide reference for the protein engineering of Baeyer-Villiger monooxygenases.
