Erweiterung des Repertoires an lichtschaltbaren unnatürlichen Aminosäuren für das Enzym‐Engineering

open access: yesAngewandte Chemie, Volume 137, Issue 38, September 15, 2025.
Enzym‐Engineering mit lichtschaltbaren unnatürlichen Aminosäuren (lsUAs) birgt ein hohes Potenzial für Anwendungen wie die Biokatalyse. Wir erweitern hier das aktuell vorhandene Repertoire mit lsUAs, welche vielseitigere Eigenschaften aufweisen, um den Weg für eine fortschrittlichere Etablierung der Lichtkontrolle in Enzymen zu ebnen. Wir berichten die

Expanding the Repertoire of Photoswitchable Unnatural Amino Acids for Enzyme Engineering

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 38, September 15, 2025.
Enzyme engineering with photoswitchable unnatural amino acids (psUAAs) has a high potential for applications such as biocatalysis. Here, we extend the current repertoire of psUAAs to include more versatile properties paving the way to more advanced photocontrol engineering.

Fluorinated Phenylazopyrazoles for Monitoring the Photoisomerization in Complex Systems

open access: yesChemistry – A European Journal, Volume 31, Issue 43, August 1, 2025.
Fluorinated azopyrazole photoswitches can be obtained in a straightforward synthesis on a wide range of substrates and isomerize efficiently under light‐irradiation. The molecular motion can be followed by 19F‐NMR spectroscopy even in complex systems, such as dopants in vesicles.
