Abstract：
:The three major chlorophyll-proteins of spinach chloroplasts were solubilized with digitonin and isolated by electrophoresis with deoxycholate. The gel bands were identified from their absorption and fluorescence spectra measured at 77 K. The slowest moving band was a Photosystem I complex (CPI); the second, a Photosystem II complex (Cpa); and the third, a chlorophyll a-b, antenna complex (LHCP). When absorption spectra (630-730 nm) of the bands were added in the proportions found in the gel, the sum closely matched the absorption of the chloroplasts both before and after solubilization. Thus these spectra represent the native absorption of the major antenna chlorophyll-proteins of green plants. Each of these spectra was resolved with a computer assisted, curve-fitting program into 8 mixed Gaussian-Lorentzian shaped components. The major, Chl a components in the 3 fractions were different both in peak positions and bandwidths. This result suggests that each chlorophyll-protein has its own unique set of chlorophyll a spectral forms or components.
