The Photosystem II pigment-protein complex, the chlorophyll alpha-protein comprising the reaction center of Photosystem II, was prepared from EDTA-treated spinach chloroplasts by digitonin extraction, sucrose-gradient centrifugation, DEAE-cellulose column chromatography, and isoelectrofocussing on Ampholine. The dissociated pigment-protein complex exhibits two polypeptide subunits that migrate in SDS-polyacrylamide gel with electrophoretic mobilities corresponding to molecular weights of approximately 43,000 and 27,000. the chlorophyll was always found in the free pigment zone at the completion of the electrophoresis. Heat-treatment of the sample (100 degrees C, 90 s) for electrophoresis caused association of the two polypeptides into large aggregates. It is concluded that these two polypeptides, 43,000 and 27,000, are valid structural or functional components of Photosystem II pigment-protein complex.
