Rb+
activates slightly, recombinant enzyme
more
enzyme activities of free and immobilized enzymes are not affected by Ca2+
more
not affected by 5 mM of Ba2+, Zn2+, Hg2+, Ni2+, Mn2+, Cu2+, Co2+, Ca2+, Na2MoO4
MnCl2
22% activation of the immobilized enzyme at 0.1 mM, 30% activation at 0.1 mM of the free enzyme
Mn2+
The transferase activity of levansucrase in the reaction mixture supplemented with Mn2+ is 100% higher than the enzyme activity in medium without metal ions, the hydrolytic activity of the levansucrase is lowered by 80%
Mg2+
activates both transfructosylation and hydrolytic activities
Fe3+
dependent on for tertiary structure, can partially be replaced by Sr2+, not Mg2+, Ba2+, and Mn2+
Fe2+
4fold increase in activity at 5 mM
Co2+
activates strongly, recombinant enzyme
Co2+
slightly activating
