Title: Competition between plastoquinone and 3-(3,4-dichlorophenyl)-1,1-dimethylurea at the acceptor side of Photosystem II
Abstract: In plastoquinone-depleted thylakoids, as obtained by n-hexane extraction, a high specifically labeled 3-(3,4-[3H]dichlorophenyl)-1,1-dimethylurea ([3H]DCMU) is displaced competitively from the membrane by the short-chain plastoquinone analogue plastoquinone-1. A binding constant Kb = 51 ± 19 μM could be calculated for plastoquinone-1. Similarly, [3H]DCMU is also competitively displaced by the Photosystem II acceptor dichlorophenolindophenol (Kb = 20 ± 3 μM).
