The specific activities (U [mg protein]−1) are the averages of no less than three technical replicates and two biological replicates (±standard error). ND, a specific activity was not determined. p-values calculated from one-way ANOVA test comparing enzymatic activity across treatments.
p < 0.05,
p < 0.01, and
p < 0.001.
Tukey post-hoc test indicates groups whose members are not significantly different. NS, no significance.
