Atomistic simulations reveal the photoactivation mechanism of a carotenoid-binding photoreceptor

Proceedings of the National Academy of Sciences, Volume 123, Number 11, March 2026.
ImportancePhotoprotection is essential for cyanobacteria to prevent light-induced damage, and orange carotenoid protein (OCP) plays a central role in this process. Although the structural changes associated with OCP photoactivation have been…
