Please wait a moment until all data is loaded. This message will disappear when all data is loaded.
CuSO4
-
1 mM, 28% inhibition of D-fructose reduction, 18% inhibition of D-sorbitol oxidation
20 mM, complete inhibition, can be restored by 20 mM Zn2+, but not by Mn2+ or Mg2+
EDTA
activity of MtDH pretreated with 10 mM EDTA for 20 min at 37°C decreases 96%. Adding 20 mM ZnCl2 to the EDTA-treated enzyme restores activity up to 80% of the control (enzyme not treated with EDTA). Adding 20 mM CoCl2 and 20 mM MnCl2 to the EDTA-treated enzyme restores activity up to 132% and 94% of the control, respectively. In contrast, adding 20 mM MgCl2 or CaCl2 does not increase the activity of the EDTA-treated enzyme.; activity of MtDH pretreated with 10 mM for 20 min at 37°C decreases 96%. Adding 20 mM ZnCl2 to the EDTA-treated enzyme restores activity up to 80% of the control. Adding 20 mM CoCl2 and 20 mM MnCl2 to the EDTA-treated enzyme restores activity up to 132% and 94% of the control, respectively
the enzyme displays a 4.37fold decrease of activity in 600 mM and about 1000fold decrease of activity in 1000 mM NaCl
NaCl
-
with increasing NaCl concentrations enzyme activity decreases, 1.5 M NaCl 74% inhibition for oxidation and 72% inhibition for reduction
-
no inhibitory effect on D-fructose reduction detected for MgSO4, CaSO4, Na2SO4, ZnSO4 and MnSO4
-
