(A) Fluorescence emission is at 678 nm for LHCaR1 reconstituted with spinach pigments (Chl a/b 2.8) whether excited at 438 nm (Chl a), 467 nm (Chl b region), or 495 nm (carotenoid region). (B) Normalized emission spectra at 678 nm (excitation at 476 nm) of samples with Chl a/b 2.8 (——) and Chl a/b 0.7 (– – – –). (Measurements were at room temperature in 5 mM Tricine-NaOH, pH 7.8/6 μg/ml Chl.)
