Ca2+
Co2+
Fe2+
Mg2+
Mn2+
sulfate
the active site of each HPS monomer contains a sulfate ion
Zn2+
-
1 mM Ca2+ is less than 50% less effective in activity stimulation than 1 mM Mg2+
-
1 mM Co2+ is less than 50% less effective in activity stimulation than 1 mM Mg2+
Co2+
-
17% as effective as Mg2+ or Mn2+ in promoting synthase activity
-
1 mM Fe2+ is less than 50% less effective in activity stimulation than 1 mM Mg2+
-
bivalent cations are essential for activity, most effective is Mg2+
Mg2+
-
5 mM, essential for activity and stability, 3-hexulose phosphate synthase is rapidly and apparently irreversibly denatured by storage in the absence of one of Mg2+
Mg2+
-
1 mM Mg2+ is absolutely required for the enzyme activity and stability
Mg2+
the enzyme requires an Mg2+-assisted formation of an enediolate intermediate for catalysis of its reaction. The active site of each HPS monomer contains a magnesium ion
-
1 mM Mn2+ is 20% less effective in activity stimulation than 1 mM Mg2+
Zn2+
-
10% as effective as Mg2+ or Mn2+ in promoting synthase activity
