the enzyme has broad pH stability between pH 3.0 and 11.0 at 4°C, and prefers weakly acidic conditions at high temperatures (85°C). More than 96% of the initial enzyme activity is retained after incubation at pH 3.0-11.0 for 1 h. The enzyme loses all activity when incubated for 15 min at pH 3.0 or 4.0, and its half-life is 14.9 min at pH 5.0. The enzyme retains 72.1% of its initial activity after 1 h at pH 6.0 in sodium citrate buffer |
