An Escherichia coli-based expression system for the Baeyer-Villiger monooxygenase (BVMO) from Xanthobacter sp. ZL5 was screened for whole-cell-mediated biotransformations. Biooxidation studies included kinetic resolutions and regiodivergent conversions of structurally diverse cycloketones. An extended phylogenetic analysis of the BVMOs currently available as recombinant systems with experimentally determined Baeyer-Villigerase activity showed that the enzyme originating from Xanthobacter sp. ZL5 clusters together with the sequences of bacterial CHMO-type BVMOs. The regio- and enantiopreferences experimentally observed for this enzyme are clearly similar to the biocatalytic performance of cyclohexanone monooxygenase from Acinetobacter as prototype for this group of BVMOs and support our previously reported family grouping.
