LITERATURE
4 - 11
the enzyme is stable at pH values ranging from 4.0 to 11.0 with more than 80% remaining activity and retains more than 90% activity after a 6 h incubation at 80°C and pH 7.0-8.0. The enzyme activity is fully retained at pH 7-8, 32% remaining at pH 9.0, but becomes inactivated in the pH range from 4.0 to 6.0
