Ultrafast excited-state isomerization in phytochrome revealed by femtosecond stimulated Raman spectroscopy

Photochemical interconversion between the red-absorbing (Pr) and the far-red-absorbing (Pfr) forms of the photosensory protein phytochrome initiates signal transduction in bacteria and higher plants. The Pr-to-Pfr transition commences with a rapid Z-to-E photoisomerization at the C₁₅Formula C₁₆ meth...
