QM/MM Methods for Biomolecular Systems

Abstract Two are better than one : Quantum mechanics/molecular mechanics (QM/MM) methods are the state‐of‐the‐art computational technique for treating reactive and other “electronic” processes in biomolecular systems. This Review presents the general methodological aspects of the QM/MM approach, its use within optimization and simulation techniques, and its areas of application, always with a biomolecular focus. magnified image Combined quantum‐mechanics/molecular‐mechanics (QM/MM) approaches have become the method of choice for modeling reactions in biomolecular systems. Quantum‐mechanical (QM) methods are required for describing chemical reactions and other electronic processes, such as charge transfer or…
