Energy and signal flow in proteins
The propagation of energetic and conformational changes in a protein, in other words, energy transfer and intramolecular signaling, plays a vital role in biomolecular function. Picosecond time-resolved infrared experiments on photoswitchable proteins provide a new and promising way to study these processes, the microscopic mechanisms of which are only little understood. To facilitate the interpretations of ongoing experiments on the villin headpiece, the WW domain, and the PDZ2 domain, we will perform extensive molecular dynamics (MD) simulations. Using nonequilibrium MD techniques, we will identify the time scales, efficiency, and pathways of the vibrational energy flow in these model proteins. Intramolecular allosteric interactions or intramolecular signaling will be studied by employing an azobenzene photoswitch, which has the potential to switch between the ligand-bound and ligand-free state of the PDZ2 domain. Extensive MD simulations of the photoinduced conformational change and intramolecular signaling will be conducted that allow us to observe the functioning of the protein in real time. Moreover, we will calculate transient infrared spectra to facilitate the direct comparison to experiment.
