However, QM methods are restricted to systems of up to a few hundred atoms. 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. 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 10 For larger systems, such as reactions involving biomolecules, mixed quantum mechanics/molecular mechanics (QM/MM) treatments have become popular.
