the state of the art of combined quantum-mechanics/molecular-mechanics (QM/MM) methods, with a focus on biomolecular systems. We provide a detailed overview of the methodology of QM/MM calculations and their use within optimization and simula-tion schemes. A tabular survey of recent applications, mostly to enzymatic reactions, is given.

In the QM/MM technique, the active region is described by means of QM calculations, while the remainder of the system is described using a MM approach. The reaction path potential (RPP) follows the ideas from the reaction path Hamiltonian of Miller, Handy and Adams for gas phase reactions but is designed specifically for large systems described with QM/MM methods. RPP is an analytical energy expression of the combined QM/MM potential energy along the minimum energy path (J. Chem. Phys. 121, 89, 2004). An expansion around the minimum energy QM/MM simulations enable researchers to model different biological processes at atomistic level and study specific properties that no other method can provid Read "Rapid QM/MM approach for biomolecular systems under periodic boundary conditions: Combination of the density‐functional tight‐binding theory and particle mesh Ewald method, Journal of Computational Chemistry" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips.

However, QM of QM/MM and other computational methods for biomolecular systems with application surveys from this area [14,15,17–20,22–26,28–36].

However, QM methods are restricted to 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 electronic excitation. Hybrid quantum mechanical and molecular mechanical (QM/MM) approaches facilitate computational modeling of large biological and materials systems.
