Crystal structure of the FRP and identification of the active site for modulation of OCP-mediated photoprotection in cyanobacteria

TL;DR: The fluorescence recovery protein (FRP) acts to dissociate the OCP from the phycobilisomes by accelerating the conversion of the active red OCP to the inactive orange form, and it is concluded that the dimer is the active form.

TL;DR: This work uses broadband two-dimensional electronic spectroscopy to study the differences in excited state dynamics of the carotenoid in the two forms of OCPO and the large inhomogeneous broadening in OCPR, providing insight into the origin of the pronounced vibrational lineshape and oscillatory dynamics observed in linear absorption and 2D electronic Spectroscopy.

TL;DR: In this article, two-dimensional electronic spectroscopy was applied to investigate the photophysics of the photoactive orange carotenoid protein, which was involved in nonphotochemical quenching in cyanobacteria.
Structural and Functional Modularity of the Orange Carotenoid Protein: Distinct Roles for the N- and C-Terminal Domains in Cyanobacterial Photoprotection

TL;DR: Key structure-function relationships in the photoprotective orange carotenoid protein are revealed; the N-terminal domain is shown to be the effector of energy dissipation; it binds to the phycobilisome and quenches fluorescence without prior photochemical activation.

TL;DR: ROA spectroscopy of the native OCPR provides a direct support for the 12 Å translocation of chromophore in the photoactivation, which was proposed by X-ray crystallography using RCP.
