P450 BM3 crystal structures reveal the role of the charged surface residue Lys/Arg184 in inversion of enantioselective styrene epoxidation

Solved crystal structures of P450 BM3 variants in complex with styrene provide on the molecular level a first explanation of how a positively charged surface residue inverts the enantiopreference of styrene epoxidation. The obtained insights into productive and non-productive styrene binding modes deepened our understanding of enantioselective epoxidation with P450 BM3.
