Table 1.
Kinetic parameters for the wild-type CotA and Q441A using ABTS as substrate.
| Laccase | Km (mM)a | kcat (s−1) | kcat/Km (s−1 mM−1) |
|---|---|---|---|
| WT | 0.079 ± 0.005 | 15.36 ± 2.41 | 194.09 |
| Q441A | 0.052 ± 0.003 | 20.48 ± 2.18 | 392.07 |
Laccase activity was calculated at 37°C with 100 mM sodium citrate buffer (pH 4.5). ABTS was chosen as substrate. Km and kcat were determined by Michaelis-Menten equation.
