Effect of pH on the activity (a) and stability (b) of IDI (L141H/Y195F/W256C) and IDI. a The optimum pH was 7.5 measured at 25 °C. The mutations did not affect the optimal pH for IDI activity, but affect IDI activity for the optimal pH. b The general trends suggested that IDI (L141H/Y195F/W256C) had better pH stability propertied compared to wild-type IDI
