    Abhishek Singharoy, Assistant Professor, Center for Applied Structural Discovery, Biodesign Institute at Arizona State University.

    Computing Free-Energy Landscapes from Molecular Dynamics Simulations

    The most probable pathways of structural transition in biomolecular complexes follow minimum free-energy pathways. Employing an implicit scheme for solving the Langevin dynamics equation, called the string method, these pathways are determined for structural transitions in molecular motors. The underlying multidimensional thermodynamic landscape is probed to determine experimentally measurable quantities such as, binding affinity, turnover rates, and energy conversion efficiencies.

    Combining in vitro and in silico Single-molecule Force Spectroscopy to Characterize Protein Mechanics

    Steered Molecular Dynamics (SMD) simulations have been used to depict the underlying molecular details of protein mechanics. At the molecular level, these behaviors are governed by mechanically active proteins.

    Watching Individual Proteins Unfold and Refold Using 1-µs Resolution Force Spectroscopy

    Protein folding occurs as a set of transitions between structural states within an energy landscape. An oversimplified view of the folding process emerges when transiently populated states are undetected because of limited instrumental resolution. To achieve state-of-the-art performance, we integrated several recent technical advances that improve the precision, stability, and accuracy of AFM-based single molecule force spectroscopy.
