ORCA is an excellent QM program for QM/MM calculations, being e.g. a fast DFT and MP2 programs and supporting electrostatic embedding (pointcharges and

In the QM/MM calculations, the ligand was described at the semiempirical PM6-DH+ level. We show that this approach yields MM → QM/MM free energy corrections that agree with those from other approaches within statistical uncertainties. The desired precision can be obtained by running a proper number of independent NE simulations.

Combined quantum mechanics/molecular mechanics (QM/MM) calculations were used to investigate the reaction mechanism of taxadiene synthase (TXS). TXS catalyzes the cyclization of geranylgeranyl diphosphate (GGPP) to taxadiene (T) and four minor cyclic products. All these products originate from the deprotonation of carbocation intermediates. If the QM and MM regions are separate molecules, having non-bonded interactions only might be sufficient. If the two regions are parts of the same molecule, it is necessary to describe the bond connecting the two sections.

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 QM and MM regions can be separated by space, i.e., one part of atoms completely belongs to the QM region and the other to the MM region – ‘weakly coupled’ QM/MM calculation. An example: a solute/solvent system. Three types of QM/MM methods exist in this category: unpolarized, polarized QM/unpolarized MM, and fully polarized. In more sophisticated implementations, QM/MM methods exist to treat both light nuclei susceptible to quantum effects (such as hydrogens) and electronic states.
