TL;DR: The results are consistent with a photoactivation mechanism for BLUF domains where signaling state formation proceeds via light-driven electron and proton transfer from Y8 to FAD, followed by a hydrogen bond rearrangement and radical pair recombination.

TL;DR: OCP functions as a light-powered molecular switch that modulates its spectroscopic properties as a response to specific changes in light environment and is proposed as a mechanism wherein the red state of OCP echinenone acts as an energy dissipator via its charge transfer state.

TL;DR: The observed large dispersion of quenching timescales observed in the protein samples that contain the native pigment favors both an inhomogeneous model and an excited-state barrier for isomerization.

TL;DR: It is suggested that Nature has used the unavoidable charge transfer processes that occur when LH pigments are concentrated to enhance and direct the flow of energy.

TL;DR: It is shown that the natural lipid environment per se does not alter the properties of LHCII, which for single complexes remain very similar to that in detergent, however, it is also shown that LHC II has the strong tendency to cluster in the membrane and that protein interactions and the extent of crowding modulate the lifetimes of the excited state in the membranes.
