Chlorophyll Composition and Photochemical Activity of Photosystems Detached from Chloroplast Grana and Stroma Lamellae

AUTOR(ES)
RESUMO

A stroma fraction that has photosystem 1 activity and grana lamellae fractions that have activities for both photosystems were isolated by differential centrifugation of a needle valve homogenate. Subsequent fractions, corresponding to photosystems 1 (F-1D) and 2 (F-2D) were isolated by digitonin treatment of the grana lamellae (P-10K) and compared with respect to their chlorophyll composition and electron transport activities.
