Structure-function-dynamics relationships in the peculiar Planktothrix PCC7805 OCP1: Impact of his-tagging and carotenoid type

Archive ouverte | Wilson, Adjélé | CCSD

International audience. The orange carotenoid protein (OCP) is a photoactive protein involved in cyanobacterial photoprotection. Here, we report on the functional, spectral and structural characteristics of the pecu...

Unifying Perspective of the Ultrafast Photodynamics of Orange Carotenoid Proteins from Synechocystis : Peril of High-Power Excitation, Existence of Different S* States, and Influence of Tagging

Archive ouverte | Niziński, Stanisław | CCSD

International audience. A substantial number of Orange Carotenoid Protein (OCP) studies have aimed to describe the evolution of singlet excited states leading to the formation of a photoactivated form, OCPR. The mos...

Is orange carotenoid protein photoactivation a single-photon process?

Archive ouverte | Niziński, Stanisław | CCSD

International audience. In all published photoactivation mechanisms of orange carotenoid protein (OCP), absorption of a single photon by the orange dark state starts a cascade of red-shifted OCP ground-state interme...
