(a) Relative activity of Xyn-2 in the presence of various cations at 5 mM and 10 mM concentrations. The amount of enzyme activity in the absence of the cations (control) was taken as 100% and the activity in the presence of each cation was expressed relative to that. (b) Influence of NaCl at high concentrations on Xyn-2 activity. The amount of enzyme activity in the absence of NaCl (control) was taken as 100% and the activities obtained in various concentrations of NaCl were expressed as a percentage to that. All reactions were performed at 20 °C, in citrate buffer (pH 5). The stars indicate a significant increase in the enzyme activity at p ≤ 0.001 (***), p ≤ 0.01 (**), and p ≤ 0.05 (*) compared to the control.
