In biocatalysis we use enzymes to accelerate chemical reactions. The advantage of enzymes over other chemical catalysts is their excellent performance in respect to reactivity, regioselectivity and enantioselectivity. The gentle environment at which they can optimally function further enhances their applicability to provide more sustainable...

Two-component-diffusible-flavomonooxygenases are versatile biocatalysts for selective epoxidation-, hydroxylation- or halogenation reactions. Their complicated molecular architecture can be simplified using photochemical regeneration of the catalytically active, reduced FADH <sub>2</sub> prosthetic group. In this contribution we provide the...

The selective oxidation of trans-2-hexen-1-ol to the corresponding aldehyde using a recombinant aryl alcohol oxidase from Pleurotus eryngii (PeAAOx) is reported. Especially using the two liquid phase system to overcome solubility and product inhibition issues enabled to achieve more than 2.200.000 catalytic turnovers for the production enzyme...

Various enzymes utilize hydrogen peroxide as an oxidant. Such “peroxizymes” are potentially very attractive catalysts for a broad range of oxidation reactions. Most peroxizymes, however, are inactivated by an excess of H<sub>2</sub>O<sub>2</sub>. The electrochemical reduction of oxygen can be used as an in situ generation method for hydrogen...

An increasing number of biocatalytic oxidation reactions rely on H <sub>2</sub> O <sub>2</sub> as a clean oxidant. The poor robustness of most enzymes towards H <sub>2</sub> O <sub>2</sub> , however, necessitates more efficient systems for in situ H <sub>2</sub> O <sub>2</sub> generation. In analogy to the well-known formate dehydrogenase to...

Photoenzymatic cascades can be used for selective oxygenation of C−H-Bonds under mild conditions circumventing the hydrogen peroxide mediated peroxygenase inactivation via in situ H<sub>2</sub>O<sub>2</sub> generation. Here, we report the “on demand” production of hydrogen peroxide via methanol assisted reduction of molecular oxygen using UV...

Peroxygenases are very interesting catalysts for specific oxyfunctionalization chemistry. Instead of relying on complicated electron transport chains, they rely on simple hydrogen peroxide as the stoichiometric oxidant. Their poor robustness against H<sub>2</sub>O<sub>2</sub> can be addressed via in situ generation of H<sub>2</sub>O<sub>2<...

A recently discovered photodecarboxylase from Chlorella variabilis NC64A ( CvFAP) bears the promise for the efficient and selective synthesis of hydrocarbons from carboxylic acids. CvFAP, however, exhibits a clear preference for long-chain fatty acids thereby limiting its broad applicability. In this contribution, we demonstrate that the...

The biocatalytic preparation of trans-hex-2-enal from trans-hex-2-enol using a novel aryl alcohol oxidase from Pleurotus eryngii (PeAAOx) is reported. As O<sub>2</sub>-dependent enzyme PeAAOx-dependent reactions are generally plagued by the poor solubility of O<sub>2</sub> in aqueous media and mass transfer limitations resulting in poor...

Deazaflavins are potentially useful redox mediators for the direct, nicotinamide-independent regeneration of oxidoreductases. Especially the O<sub>2</sub>-stability of their reduced forms have attracted significant interest for the regeneration of monooxygenases. In this contribution we further investigate the photochemical properties of...

Peroxygenases offer an attractive means to address challenges in selective oxyfunctionalization chemistry. Despite this, their application in synthetic chemistry remains challenging due to their facile inactivation by the stoichiometric oxidant H<sub>2</sub>O<sub>2</sub>. Often atom-inefficient peroxide generation systems are required, which...

Recent developments in microfluidic and nanofluidic technologies have resulted in development of new chip-based microfluidic calorimeters with potential use in different fields. One application would be the accurate high-throughput measurement of enzyme activity. Calorimetry is a generic way to measure activity of enzymes, but unlike...
