Role of hydrogen bond alternation and charge transfer states in photoactivation of the Orange Carotenoid Protein

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 (oxocarbenium cation) state. This study suggests the...
