The goal of the project is to develop numerical methods and computational strategies to understand the energetics and dynamics of chemical reactions in complex environments and to apply them to chemically and biologically relevant systems. Using a combination of adiabatic reactive molecular dynamics (ARMD), improved force fields, potential energy surface ``morphing'' procedures, and electronic structure calculations, reactions including hydrogen/proton-transfer, ligand-binding and ligand-transfer are investigated at a quantitative level. The ARMD method will be generalized to treat molecule-transfer, ligand exchange and vibrational-assisted dissociation reactions. Chemical and biochemical systems of particular interest include ligand exchange (Fe(II)--NO+O2->Fe(II)--O2+NO) in truncated Hemoglobin, ligand transfer in cytochrome c oxidase (Fe-CO+Cu -> Fe+Cu-CO), hydrogen transfer in malonaldehyde and acetylacetone, and the vibrationally assisted dissociation of sulfuric acid (SO4H2). For all systems detailed experimental data is available which allows to refine the interactions potentials required to describe the energetics, and to characterize the dynamics from extended atomistic simulations. Where possible and appropriate, interaction potentials will be derived from iteratively refined, dynamics-based potential energy functions which is an approach that was recently developed in our group. Given that ligands such as nitric oxide play a central role in our investigations, the distributed multipole (DM) approach will be extended to radicals to quantitatively describe O2 and NO interacting with the protein environment.
