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.
