Absorption spectra (A), fluorescence excitation spectra measured at 675 nm (B) and fluorescence emission spectra (C) recorded upon excitation at 465 nm were recorded using WT Fcp purified on gel filtration (dashed line), FcpA_His after IMAC (solid line) and FcpA_His further purified on gel filtration (dotted line) at a Chl concentration of ∼0.3 μg ml⁻¹, and normalized to the Q_Y absorption (A), the maximum in the Soret (B) and the maximal Chl a emission (C).
