| (R)-BGE | 75.2 ± 2.9 | −0.23 ± 0.05 | 72.68 ± 1.98 | 72.90 ± 2.01 | 240 ± 1.3 | 342 |
| (S)-BGE | 26 ± 1.6 | −5.69 ± 0.29 | 23.48 ± 2.13 | 29.17 ± 1.48 | 96 ± 1.9 |
All values were calculated as average of 3 sets of experimental replicates and were considered statistically significant with p < 0.005. Arrhenius energy (Ea) of activation was calculated by plotting the ln k where k is rate constant at each temperature against reciprocal of temperature (1/T) in kelvin.
