Density Functional Theory Study on Metal-Binding Energies for Human Serum Transferrin-Metal Complexes

Figure 2

Plot of the absolute value of the calculated binding energy ( | Δ 𝐸 | , kcal/mol) between each metal ion and BS versus the Experimentally obtained l o g 𝐾 1 value [6]. The open squares denote the absolute values of the binding energies in vacuo (intrinsic binding energies, | Δ 𝐸 𝑖 | ), and the correlation coefficient is 𝛾 = 0 . 8 6 3 . The filled circles denote the absolute values of the binding energies with the solvation effect (real binding energies, | Δ 𝐸 𝑟 | ) and 𝛾 = 0 . 9 5 8 .
