The models are determined from quantum mechanics, molecular mechanics, experimental results, and these combinations.
WebIn summary, ff19SB, when combined with a more accurate water model such as OPC, should have better predictive power for modeling sequence-specific behavior, protein mutations, and also rational protein design. Of the explicit water models tested here, we recommend use of OPC with ff19SB. Supporting Information Web↑ L. F. Abascal, E. Sanz, R. García Fernández, and C.
