Kim, Jinhyun (author), Um, Yunna (author), Han, Seunghyun (author), Hilberath, T. (author), Kim, Yong Hwan (author), Hollmann, F. (author), Park, Chan Beum (author)The pulp and paper manufacturers generate approximately 50 million metric tons of lignin per annum, most of which has been abandoned or incinerated because of lignin's recalcitrant nature. Here, we report bias-free photoelectrochemical (PEC) oxidation of lignin coupled with asymmetric hydrogenation of C=C bonds. The PEC platform consists of a...journal article 2022

Yoon, Jaeho (author), Lee, S.H. (author), Tieves, F. (author), Rauch, M.C.R. (author), Hollmann, F. (author), Park, Chan Beum (author)We report visible light-driven, asymmetric hydrogenation of C=C bonds using an ene-reductase from Thermus scotoductus SA-01 (TsOYE) and a light-harvesting dye (rose bengal, RB) co-immobilized in an alginate hydrogel. Highly efficient encapsulation of RB in alginate hydrogel was achieved using the intrinsic affinity between TsOYE and RB,...journal article 2019

Willot, S.J. (author), Fernandez Fueyo, E. (author), Tieves, F. (author), Pesic, M. (author), Alcalde, Miguel (author), Arends, I.W.C.E. (author), Park, Chan Beum (author), Hollmann, F. (author)Peroxygenases require a controlled supply of H<sub>2</sub>O<sub>2</sub> to operate efficiently. Here, we propose a photocatalytic system for the reductive activation of ambient O<sub>2</sub> to produce H<sub>2</sub>O<sub>2</sub> which uses the energy provided by visible light more efficiently based on the combination of wavelength...journal article 2019

Kim, Jinhyun (author), Lee, S.H. (author), Tieves, F. (author), Choi, Da Som (author), Hollmann, F. (author), Paul, C.E. (author), Park, Chan Beum (author)Light-driven activation of redox enzymes is an emerging route for sustainable chemical synthesis. Among redox enzymes, the family of Old Yellow Enzyme (OYE) dependent on the nicotinamide adenine dinucleotide cofactor (NADH) catalyzes the stereoselective reduction of α,β-unsaturated hydrocarbons. Here, we report OYE-catalyzed asymmetric...journal article 2018
