title: Enrichment of photosystem I reaction center chlorophyll from spinach chloroplasts.
abstract: The reaction center chlorophyll of Photosystem I in spinach chloroplasts was highly enriched. Preparations having 5-9 chlorophylls per 1 P700 were obtained by treating the Photosystem I particles prepared by digitonin treatment of chloroplasts with wet diethyl ether. All P700 present in the extracted particles was found to be photoactive, undergoind oxidation upon illumination.
