At the end of my PhD, we initiated a campaign on a photoenzymatic process using red light to catalyze radical reactions, which has now been published in Chem Cell Press. Photoenzymes, a class of biocatalysts using photonic energy, have gained attention due to their latent photochemical functions. In this field, there is a need to spectrally tune the photoenzymatic chromophore to improve enzyme stability and scalability. We engineered a flavin-dependent "ene"-reductase to utilize red light for a radical cyclization, previously achieved with cyan light. By targeting residues throughout the protein, we optimized its red-light activity, scaling the reaction to 10 grams. Mechanistic studies revealed that protein engineering alters substrate-binding conformations, resulting in red absorptions. Surface mutations further tuned the light-absorbing complex, revealing allosteric regulation in artificial photoenzymes, a novel discovery. This work demonstrates the potential for tuning photoenzymes with directed evolution, advancing chemical manufacturing. Now all my PhD works are concluded.

Yu Ma will be defending her #PhD dissertation on Friday 8 November 2024. During her studies, Yu Ma focused on designing and optimising #fusionenzymes for efficient oxyfunctionalisation in non-aqueous media. Her research aimed to address the inherent challenges of Baeyer-Villiger Monooxygenases (BVMOs), whose applications are limited by #enzyme instability, product/substrate inhibition, and cofactor dependency. By engineering novel fusion enzymes combining BVMOs and alcohol dehydrogenase, she explored how linker design and enzyme orientation affect catalytic efficiency in linear cascade reactions. Her work not only enhanced enzyme stability and activity but also expanded the use of these fusion enzymes in biphasic systems and deep eutectic solvents. Her findings demonstrate the potential of fusion enzymes to improve oxyfunctionalisation reactions, providing valuable insights for enzyme-driven industrial processes in non-aqueous media. The PhD study was completed at Department of Biological and Chemical Engineering (BCE), Faculty of Technical Sciences - Aarhus University. ▶ Time: Friday, 8 November 2024 from 14:00 ▶ Place: Building 3130, room 303, Gustav Wieds Vej 10C, 8000 Aarhus ▶ Title of PhD thesis: Design of Enzymatic Oxyfunctionalizations Catalyzed by Fusion Enzymes in Non-aqueous Media Yu Ma’s main supervisor is Professor Selin Kara.
