Popis: Phenazine methosulphate mediated cyclic phosphorylation suppressed by heptane extraction or galactolipase treatment of spinach chloroplasts is restored by β -carotene, in 100% and 50%, respectively. Xanthophylls are not able to reconstitute this reaction. β-Carotene replaces galactolipids in reactivation of galactolipase treated chloroplasts, indicating a nonspecific effect of lipids in photosystem I dependent reactions.
