Table 2. Kinetic parameters for the hydrolysis of 3PET by wild-type (WT) LCC and its variants in 50 mM citrate, 100 mM phosphate (pH 8.0) at 45 °C. The kcat, KM, and n-values were determined with the Hill equation (Fig. S12).
| Enzyme | k cat (s−1) | K M (µM) | k cat/KM (s−1 mM−1) | n-value |
|---|---|---|---|---|
| WT | 4.04 ± 0.31 | 114 ± 12 | 35.6 ± 1.4 | 1.60 ± 0.09 |
| V212T | 4.77 ± 0.13 | 127 ± 14 | 36.5 ± 1.3 | 1.58 ± 0.12 |
| L102F–V212T | 6.73 ± 0.14 | 148.0 ± 2.1 | 45.4 ± 0.6 | 1.530 ± 0.066 |
