Table 2. Summary of PISA analyses of buried surface areas and ΔG values of the four unique NSs-ΔNΔC tetramers present in the crystal lattice. ΔG^sol and ΔG^diss are free energy of solvation (negative values indicate favorable process), and free energy of dissociation of assembly (positive values indicate stable association), respectively.
