Biocatalysis and the Production of Flavor Compounds

The biocatalytic reduction of activated alkenes by ene reductases offers an bio-based alternative to metal- or organocatalyzed double bond reduction. In our recent publication, we describe a new biocatalytic process to reduce 2E-decenal.

The halogenase toolbox is growing: Re-programming and optimization of a L-proline cis-4-hydroxylase for the cis-3-halogenation of its native substrate

Over 5000 halogenated natural products are described and around 25% of small molecular drugs are halogenated. Thus, strategies are needed to incorporate halogens in a selective and sustainable way.
