activity range, enzyme activity increases gradually with the increase of pH. When pH reaches the range of pH 8-8.5, the enzyme displays the highest activity. With the further increase of pH to about pH 9, the activity of the enzyme decreases slightly. At pH 9-10, the activity of OcUGlcAE3 increases gradually, and reaches the highest activity again at pH value of 10. Above the pH 10.0, the activity decreases, 80% of maximal activity at pH 12.0.
