pH 5.5: about 35% of maximal activity, pH 8.0: about 50% of maximal activity
additional information
-
high pH sensitivity of enzyme, highest activity at apoplastic pH of 4.9, no activity above apoplastic pH of 5.3. Nitrate increases pH value, thus inhibiting enzyme activity, ammonium decreases pH value. Nitrate together with hydrogen carbonate, a combination typical for calcareous soils, has strongest enzyme depressing effect
