What it's about

Course content will vary from year to year. In 2001, the theme was Protein Dynamics, focusing on the recent measurements of the mechanical properties of single proteins. Through reading the literature, we became acquainted with laser tweezers and atomic-force microscope measurements, most notably on the muscle protein titin. The fundamental molecular processes underlying intermolecular forces and protein folding were presented and used to build simple models to compare with the published data on protein behavior.

Mechanics of Motor Proteins and the Cytoskeleton, Jonathon Howard (2001).

It is possible to do mechanical experiments on single protein molecules and measure the applied force needed to achieve a certain change in protein length. Theories to reproduce these findings have been developed, though our general understanding of protein dynamics is still rudimentary.
