“How Life Sees Light: Photosensory Receptor Activation Mechanisms Revealed by Time-Resolved Electronic and Vibrational Spectroscopy”

Nature has evolved a wide array of photosensory systems to enable organisms to sense and respond to their light environment. Photosensory receptor proteins provide unique opportunities to understand the essential principles of signal transduction and protein function because they can be activated by light, rendering them amenable to advanced biophysical experimental methods. Here, I will show how time-resolved spectroscopy from the femtosecond to millisecond timescale, in particular UV-visible, femtosecond stimulated Raman and mid-infrared spectroscopy may be employed to gain considerable insights into their photoactivation mechanisms.
