LITERATURE
Cs+
CsCl
-
the enzyme is maximally active in the presence of 1.2 M KCl. Activity in the presence of RbCl and CsCl is similar to that observed in the presence of KCl
K+
KCl
-
the enzyme is maximally active in the presence of 1.2 M KCl. Activity in the presence of RbCl and CsCl is similar to that observed in the presence of KCl
Li+
-
absolute requirement for both monovalent and divalent cations, when Mg2+ fills the requirement for divalent cation, K+ and Rb+ are the most active monovalent cations, NH4+, Na+, Cs+ and Li+ are decreasingly active
Mg2+
Na+
NaCl
-
stimulates, yields 50% of the activity observed in equimolar KCl
NH4+
Rb+
RbCl

Cs+
-
absolute requirement for both monovalent and divalent cations, when Mg2+ fills the requirement for divalent cation, K+ and Rb+ are the most active monovalent cations, NH4+, Na+, Cs+ and Li+ are decreasingly active
K+
-
absolute requirement for both monovalent and divalent cations, when Mg2+ fills the requirement for divalent cation, K+ and Rb+ are the most active monovalent cations
Mg2+
-
absolute requirement for both monovalent and divalent cations, for optimal activity the concentration of Mg2+ must equal or exceed the concentration of ATP
Mg2+
-
most active at a Mg2+ concentration of 1 mM. Mg2+ can not be replaced by Mn2+. ATP/Mg2+ in the ratio of 1:2 forms the actual substrate for ketohexokinase activity
Na+
-
absolute requirement for both monovalent and divalent cations, when Mg2+ fills the requirement for divalent cation, K+ and Rb+ are the most active monovalent cations, NH4+, Na+, Cs+ and Li+ are decreasingly active
NH4+
-
absolute requirement for both monovalent and divalent cations, when Mg2+ fills the requirement for divalent cation, K+ and Rb+ are the most active monovalent cations, NH4+, Na+, Cs+ and Li+ are decreasingly active
Rb+
-
absolute requirement for both monovalent and divalent cations, when Mg2+ fills the requirement for divalent cation, K+ and Rb+ are the most active monovalent cations, NH4+, Na+, Cs+ and Li+ are decreasingly active
