Blending Baeyer-Villiger monooxygenases: using a robust BVMO as a scaffold for creating chimeric enzymes with novel catalytic properties

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.
