Yaroshevich et al. present a chemical reaction mechanism of a 35-kDa blue light-triggered photoreceptor, the Orange Carotenoid Protein (OCP). They find that photoactivation critically involves the transient formation of a protonated ketocarotenoid (o

Time-resolved femtosecond-stimulated Raman spectroscopy (FSRS) provides valuable information on the structural dynamics of biomolecules. However, FSRS has been applied mainly up to the nanoseconds regime and above 700 cm−1, which covers only part o

Blue light sensing using flavin (BLUF) domains constitute a family of flavin-binding photoreceptors of bacteria and eukaryotic algae. BLUF photoactivation proceeds via a light-driven hydrogen-bond switch among flavin adenine dinucleotide (FAD) and gl
