Direct measure of functional importance visualized atom-by-atom for photoactive yellow protein: application to photoisomerization reaction.

Photoreceptor proteins serve as efficient nano-machines for the photoenergy conversion and the photosignal transduction of living organisms. For instance, the photoactive yellow protein derived from a halophilic bacterium has the p-coumaric acid chromophore, which undergoes an ultrafast photoisomerization reaction after light illumination. To understand the… CONTINUE READING
