Abstract

The thermostable Baeyer-Villiger monooxygenase (BVMO) phenylacetone monooxygenase (PAMO) is used as a scaffold to introduce novel selectivities from other BVMOs or the metagenome by structure-inspired subdomain exchanges. This yields biocatalysts with new preferences in the oxidation of sulfides and the Baeyer-Villiger oxidation of ketones, all while maintaining most of the original thermostability.

摘要

热稳定的 Baeyer-Villiger 单加氧酶(BVMO)苯乙酮单加氧酶(PAMO)可作为支架,通过结构启发的亚结构域交换,从其他 BVMO 或宏基因组中引入新的选择性。这产生了具有新型硫化物氧化和 Baeyer-Villiger 酮氧化偏好的生物催化剂,同时保持了大部分原始的热稳定性。
