Abstract

Treatment of whole and fractionated plant tissues with hydrophilic and hydrophobic solvent mixtures of varied volume ratio liberates two chlorophyll (Chl) a′ molecules from the photosystem (PS)I core when the solvent hydrophilicity exceeds a critical level, whereas only one molecule is extracted in hydrophobic media. The PSI core proteins, PSI-A and PSI-B, which form a heterodimer, appear to bind one Chl a′ molecule each, in local environments significantly different regarding their hydrophilicity or hydrophobicity.
