QM/MM methods offer the advantage of lower computational cost than a QM calculation for a large system, and allow modeling of processes such as chemical reactions, which cannot be modeled simply by typical MM methods. Part of the system, e.g., the active site of an enzyme, is treated by a quantum mechanical electronic structure method, which

The terms QM and MM stand for the atoms in the QM and MM subsystems,respectively.Thesubscriptsindicatetheleveloftheoryat which the potential energies (V ) are computed. The most widely used subtractive QM/MM scheme is the ONIOM method, devel-oped by the Morokuma group (6, 7), and is illustrated in Fig. 2.

11 In this approach the system is decomposed 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. A quantum mechanical/molecular mechanical (QM/MM) approach based on the density-functional tight-binding (DFTB) theory is a useful tool for analyzing chemical reaction systems in detail. In this study, an efficient QM/MM method is developed by the combination of the DFTB/MM and particle mesh Ewald (PME) methods. ombined 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 pro-cesses, such as charge transfer or electronic excitation.

QM/MM papers since we shall quote only a small selection of these in the following. The QM/MM approach is by now established as a valuable tool for modeling large biomolecular systems, but it is also often applied to study processes in explicit solvent and to investigate large inorganic/organometallic and solid-state systems. Methodological QM/MM simulations enable researchers to model different biological processes at atomistic level and study specific properties that no other method can provid accuracy of a QM/MM treatment at the computational cost of classical MD. This allows sampling times far beyond the limits of the QM/MM method and the calculation of properties with long correlation times, such as thermodynamic averages involving slow motions of large biomolecules.
