Cutinase activity of MtCut. (A) MtCut, ICCG, and IsPETase protein purity. The impact of temperature (B) and pH (C) on cutinase activity of MtCut and its mutants. (D) Thermal inactivation profiles of MtCut and its mutants in the absence/presence of 1 mM calcium ions or EDTA at 30°C. All the tests used pNP butyrate as substrate.
