Isothermal Titration Calorimetry (ITC) values of Ageritin in the presence of Mg2+, Ca2+, and Zn2+ ions.

ITC Experimental Values
N of Sites KITC (M−1) ΔH (Kcal mol−1)
Mg2+ 3 3.25 × 106 −1.6
Ca2+ 1 7.68 × 105 −13.1
Zn2+ 4 1.77 × 107 −9.9

N of sites: number of protein binding sites for metal ions; KITC: binding constant or isothermal titration calorimetry association constant, ΔH: enthalpy related to KITC.
