We provide an overview of the IMPACT molecular mechanics program with an emphasis on recent developments and a description of its current functionality. With respect to core molecular mechanics technologies we include a status report for the fixed charge and polarizable force fields that can be used with the program and illustrate how the force fields, when(More)
A QM–MM method, using our previously developed frozen orbital QM–MM interface methodolgy, is presented as a general, accurate, and computationally efficient model for studying chemical problems in a protein environment. The method, its parametrization, and a preliminary application to modeling cytochrome P-450 chemistry are presented.
