In the loop: Engineering of the surfaceloop in haloalkanedehalogenases affects their enantiodiscrimination behavior. The temperature dependence of the enantioselectivity (lnE versus 1/T) of β‐bromoalkanes by haloalkanedehalogenases is reversed (red data points) by deletion of the surfaceloop; the selectivity switches back when an additional single‐point mutation is made. This behavior is not observed
