Figure 5.

Active site structure of (a) TfCut2 and (b) PETase. Stick models show the catalytic serine and identified amino acids based on sequence comparison. (c) Three-h lcPET degradation rates (1.2 cm² mL⁻¹) of 1 µM TfCut2 mutants in the absence or presence of surfactant at 65 °C. The error bars denote the standard deviation calculated from three different experiments.
