Résumé
Phytochromes are photoreceptors that upon light absorption initiate a physiological reaction cascade. The starting point is the photoisomerization of the tetrapyrrole cofactor in the parent Pr state, followed by thermal relaxation steps culminating in activation of the physiological signal. Here we have employed resonance Raman (RR) spectroscopy to study the chromophore structure in the primary photoproduct Lumi-R, trapped between 130 and 200 K. The investigations covered phytochromes from plants (phyA) and prokaryotes (Cph1, Agp1, CphB, and
