Graphical Abstract

Gezielte Mutationen der Oberflächenschleife von Halogenalkan-Dehalogenasen haben Auswirkungen auf die Enantiodiskriminierung. Die Temperaturabhängigkeit der Enantioselektivität (siehe lnE-1/T-Kurve) von β-Bromalkanen kehrt sich bei einer Deletion der Oberflächenschleife um (rote Datenpunkte), was bei Einführung einer zusätzlichen Einzelpunktmutation wieder rückgängig gemacht wird; bei α-Bromestern findet keine Änderung statt.
