Résumé
Cyanobacteriochromes (CBCRs) are photoreceptor proteins that photoconvert between two parent states and thereby regulate various biological processes. An intriguing property is their variable ultraviolet-visible (UV-vis) absorption that covers the entire spectral range from the far-red to the near-UV region and thus makes CBCRs promising candidates for optogenetic applications. Here, we have studied Slr1393, a CBCR that photoswitches between red- and green-absorbing states (Pr and Pg, respectively). Using UV-vis absorption, fluorescence, and resonance Raman (RR) spectroscopy, a further orange-absorbing state O
