Interactions Energies (kCal/mol) between the Two Domains Calculated Using the Optimized Structures with the FF12SB Force Field of Amber.12

	Total Energy of Domain α and β	Energy of Domain α	Energy of Domain β	Interaction Energy between Domains α and β
Blg1	−3207.8	−732.0	−1744.8	−731.0

Note.—The energies given in the table contain only the nonbonded (electrostatic and van der Walls) terms because the interaction energy between the domains results only from those two components under the current pairwise additive energy scheme.
