Table . Kinetic parameters of HheG wild type and mutant M45F in the azidolysis of cyclohexene oxide (1). First, the epoxide concentration was varied while keeping the azide concentration constant at 60 mM; afterwards, the azide concentration was varied while fixing the epoxide concentration at 100 mM. The Hill equation was used to fit the resulting data in OriginPro (Figure ). Data for HheG wild type were taken from Staar et al. (2024), as the exact same reaction conditions have been applied.
