Abstract:
:In this article, we review how molecular modeling techniques can be used to shed light on how water and organic solvents influence the reactivity of enzymes. The application of thermodynamics-based models allowed the first qualitative predictions on the selectivity of many reaction types. However, it was with the application of quantum mechanical/molecular mechanical (QM/MM) methods that quantitative models of actual reactivity patterns could be realistically formulated.
