Please wait a moment until all data is loaded. This message will disappear when all data is loaded.
Ca2+
CaCl2
-
activates the purified enzyme by 50% at 1-100 mM, activates at 0.005% in the culture medium, activation is lowered in presence of MgSO4
Co2+
Cu2+
Hg2+
K+
Mg2+
MgSO4
-
no effect on purified enzyme, activates at 0.005% in the culture medium, activation is lowered in presence of CaCl2
Mn2+
Na+
Sodium arsenate
-
slightly promotes the activity of PNL (110% relative activity at 1 mM)
additional information
Ca2+
-
optimal concentration above pH 4.5: 50 mM. Optimal cocentration below pH 4.5: 30 mM
Ca2+
-
slightly promotes the activity of PNL (105% relative activity at 1 mM)
Ca2+
-
activity increases with the increase in Ca2+ concentration
Ca2+
-
at pH values above the optimum, calcium ions can increase pectin lyase activity or even shift the pH optimum into more acidic range. No effect on enzyme activity toward highly methylated citrus pectin is displayed by CaCl2 at the salt concentration of 0-0.1 M at pH 8.0
Co2+
-
slightly promotes the activity of PNL (114% relative activity at 1 mM)
-
optimal concentration above pH 4.5: 300 mM. Optimal concentration below pH 4.5: 100 mM
Na+
-
slightly promotes the activity of PNL (108.3% relative activity at 1 mM)
-
EDTA and metal ions have very little effect on the enzyme
additional information
-
Ca2+ and Co2+ have no significant effects on activity
