Universality of Ultrafast Protein Dynamics of Rhodopsins Revealed by Femtosecond Time-Resolved Ultraviolet Stimulated Raman Spectroscopy

摘要

Rhodopsins, which constitute an important group of photoreceptor proteins, possess a retinal chromophore. So far, it has been widely believed that the photoisomerization of the chromophore is the first event of the photoreaction to trigger the subsequent biological processes.
