Mechanistic simulation of enzyme catalysis \r\rEnzymes play critical roles in life processes by catalyzing vastly diverse chemical reactions, ranging from simple carbon dioxide hydration to complicated long-range electron / radical transfer and photochemical process. Compared with uncatalyzed processes, enzymes can significantly speed up the reactions. Origin of the catalytic power of enzymes constitutes an intellectual challenge to our understanding of nature; the knowledge of which would immediately contribute to biomedicinal research such as drug design. Development of efficient simulation methods for accurate modeling of enzyme catalysis is our focal point, which requires research in both quantum mechanical computation methods and statistical phase-space sampling techniques. \r\r\r2. Protein structure, dynamics and recognition \rAlthough the functions of protein molecules are ultimately determined by the primary sequences, the thermodynamics and kinetics of the functioning process are direct results of the interplay between protein structure and dynamics. A complete picture of the energy landscape of protein molecule is the key to the understanding of protein functions. We are interested in the correlation between protein structure and dynamics, in particular how this correlation was shaped by the functioning requirement in the thermodynamic evolution process. Understanding the hierarchic organization of protein function and dynamics, in both temporal and chemical spaces, is our final goal. \r\r3. Multi-scale computer simulation of biomolecular processes \rMany important biomolecular processes are participated by multiple protein/DNA/ RNA molecules and span long timescales. We are interested in developing multi-scale computer simulations to reveal the molecular details of these processes. \r\r4. Molecular design \rThis project applies aforementioned computational methods to the design of new molecules for medicinal or economic significance. The questions we like to explore are: \r(1) Based on the atomistic and even electronic information available for the transition state of an enzyme-catalyzed reaction, can we design new and effective inhibitors? \r(2) Can we design a new enzyme bottom-up from a desired reaction mechanism?"""近期论文
