Update: Enzymatische Synthese für industrielle Anwendungen

Angewandte Chemie, Volume 137, Issue 27, July 1, 2025.
Die Biokatalyse hat sich zu einer nachhaltigen und wettbewerbsfähigen Alternative zur herkömmlichen chemischen Synthese entwickelt und ermöglicht die enzymbasierte Herstellung nicht nur von chemischen Grundstoffen, sondern auch von (nicht natürlichen) Aminosäuren, (seltenen) Zuckern und synthetischen Nukleotiden.

Learning from Protein Engineering by Deconvolution of Multi‐Mutational Variants

Angewandte Chemie International Edition, Volume 63, Issue 36, September 2, 2024.
First derivative of a typical experimental enzyme fitness pathway landscape mapped on the basis of ΔG values, in this case of 24 trajectories in the deconvolution of a 4‐mutational variant. Green areas indicate negative slopes and define trajectories involved in energetically favored stages, while red areas indicate positive slopes representing ...
