It is important to state that these findings valid only in the context of the other force field parameters. Cooperativity of folding and stability of any secondary structural element are complex functions of the entire set of force field parameters, including some not considered here explicitly such as sidechain torsion potentials. To further improve cooperativity in homo-oligomer coarse-grained models, it will likely be necessary to move beyond ad hoc force field parameter scans, and instead use gradient or global optimization techniques.
