Our simulation results show that this adaptive QM/MM scheme is numerically stable, at least for the case studied in this work. Furthermore, this method also offers an inexpensive way to examine the convergence of the QM/MM calculation with respect to the size of the QM region. DOI: 10.1021/acs.jctc.0c01149 This tutorial describes a general procedure for a QM/MM study of a biochemical system using Gaussian and GaussView with the help of the PERL toolkit TAO. This tutorial is designed for users with some basic experience with Gaussian, GaussView and Unix/Linux systems. 2018-10-19 As far as I know, there is no routine to perform transition state optimization in AmberTools (sander), either full MM or QM/MM.

The ONIOM method is a computational approach developed by Morokuma and co-workers. ONIOM is a hybrid method that enables different ab initio or semi-empirical methods to be applied to different parts of a molecule/system in combination to produce reliable geometry and energy at reduced computational cost. The ONIOM computational approach has been found to be particularly useful for modeling biomolecular systems as well as for transition metal complexes and catalysts. Ala341:C as MM atom (num.
