Optimum pH characteristics and stability against pH of BglA. (a) Enzyme activity of BglA (●) plotted against different pH (4–10). Maximum activity can be noticed at an optimum pH, i.e., 7.0; (b) residual activity comparison as bar graph of BglA showing actual activity (black bars) at different pH values and residual activity (Grey bars) plotted after incubation at different pH values irrelatively and an extent of decrease in the activity at each pH value can be seen.
