From: Structures of a phycobilisome in light-harvesting and photoprotected states
a, Representative coomassie blue-stained SDS-PAGE. The purification was repeated at least three times with similar results. b, UV-Vis absorption spectra of the OCPO (inactive form) and OCPR (active form). c, Fluorescence quenching of 1:20 (PBS:OCP). The PBS is biotinylated. d, Titration PBS:OCP fluorescence quenching at various ratios indicated. e–g, Close-up view of the interaction between OCP and the PBS with the supporting densities.
