Enzymatic activity and stability. (a) Determination of optimal pH. (b) Enzymatic stability with respect to pH. (c) Determination of optimal temperature. (d) Enzymatic stability with respect to temperature. The enzymatic activity and stability were determined as described in the Materials and Methods. One unit of PG activity was defined as one μmol/L of GA released by enzyme min-1.
