The computational chemistry and simulations group led by Hans Senn uses combined "molecular mechanics" (MM) and quantum-mechanical (QM) computer simulations to get insight into chemical reactions, in particular catalytic reactions. Combined QM/MM methods describe only the part of the molecule where the reaction is taking place with an expensive QM method and use MM for the remainder. They are especially suited for enzyme reactions, where the reaction is confined to the "active site". Enzymes are involved in virtually all chemical transformations in living organisms and computer simulations provide a detailed picture at the atomic and molecular level of how the catalyst works. One obtains information about the reaction rates and the overall energetics of the processes as well as about the properties of the molecules involved in the reaction, including the catalysts themselves, which helps their identification in experiments.
