FIGURE 3.
Spectroscopic properties of LHCb9 reconstituted in vitro. A, comparison of LHCb9.1 and LHCb9.2 absorption spectra (black and red, respectively) with barley HvLHCb2 (blue). B, red region of spectra shown in A. C, fitting of LHCb9.2 absorption spectrum (black) with Chl absorption forms. Chl b and Chl a forms are shown in cyan and green, respectively. The two red-most Chl a forms, with a maximum at 683 and 690 nm, are shown in blue. D, low temperature fluorescence spectra upon excitation at 500 nm of LHCb9.1, LHCb9.2, and barley HvLHCb2, shown in black, red, and blue, respectively. All spectra are normalized to the maximum value in the Qy region. a.u., arbitrary units.
