QM and MM Methods: Obtaining an Atomic and Electronic View of Nature

We will present our recent method development to map electronic and atomic coordinates for complex biological processes. 1) The atomic detailed mechanism of long range conformational changes remains a great challenge. Many biologically relevant processes, involving large domain motions or quaternary rearrangement, occur in the millisecond time scale, out of the reach of Molecular Dynamic techniques. PELE (Protein Energy Landscape Exploration), combines protein structure prediction techniques with a metropolis algorithm and is capable of fast mapping the slow motion energy landscape. 2) Electron transfer is one of the simplest but crucial reactions in biochemistry present in almost. Mixed quantum mechanics molecular mechanics methods (QMMM) offer a valuable computational tool for understanding the electron transfer pathway in protein-substrate and protein-protein complexes. By selectively turning on/off different residues in the quantum region, we have developed a novel approach capable of obtaining the electron pathway for short and large range interactions.
