pH and temperature profiles of alkaline pectin lyase, a Optimum pH, b Optimum temperature, c Stability of PGLA and PGLA-rep4 at pH range, d Thermal stability of PGLA and PGLA-rep4 in glycine-NaOH buffer (pH 11.0) at 60 °C—the activities of all enzymes were determined under standard enzyme assay conditions using 0.2% apple pectin as substrate and all data are presented as the mean of three experiments; error bars represent standard deviation
