Elucidating the Role of O2 Uncoupling for the Adaptation of Bacterial Biodegradation Reactions Catalyzed by Rieske Oxygenases

Microorganisms exposed to xenobiotics quickly adapt their enzymatic machinery. The evolution of these enzymes enables the degradation of new molecules that are structurally related to the original target substrates.

Effective engineering of a ketoreductase for the biocatalytic synthesis of an ipatasertib precursor

In Communications Chemistry we report the evolution of a ketoreductase that catalyzes a key synthesis step - the reduction of the prochiral ketone to the desired (R,R)-trans alcohol intermediate - with high efficiency in an industrial set-up.

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.
