Function

[BVMO_PARL1] Catalyzes a Baeyer-Villiger oxidation reaction, i.e. the insertion of an oxygen atom into a carbon-carbon bond adjacent to a carbonyl, which converts ketones to esters or lactones using NADPH as an electron donor. Besides cycloalkanones, can use cyclic alpha,beta-unsaturated ketones as substrates, leading to enol-lactones. Can also act on methylated cycloalkanones and methylated cycloalkenones with high enantioselectivity in some cases.^[1]

Publication Abstract from PubMed

Baeyer-Villiger monooxygenase (BVMO) catalyzes insertion of an oxygen atom into aliphatic or cyclic ketones with high regioselectivity. The BVMOs from Parvibaculum lavamentivorans (BVMOParvi) and Oceanicola batsensis (BVMOOcean) are interesting because of their homologies, with >40% sequence identity, and reaction with the same cyclic ketones with a methyl moiety to give different products. The revealed BVMOParvi structure shows that BVMOParvi forms a two-domain structure like other BVMOs. It has two inserted residues, compared with BVMOOcean, that form a bulge near the bound flavin adenine dinucleotide in the active site. Furthermore, this bulge is linked to a nearby alpha-helix via a disulfide bond, probably restricting access of the bulky methyl group of the substrate to this bulge. Another sequence motif at the entrance of the active site (Ala-Ser in BVMOParvi and Ser-Thr in BVMOOcean) allows a large volume in BVMOParvi. These minute differences may discriminate a substrate orientation in both BVMOs from the initial substrate binding pocket to the final oxygenation site, resulting in the inserted oxygen atom being in different positions of the same substrate.
