additional information PS II membrane fragments that contain a membrane pool of PQ and are largely devoid of PS I and Cyt b6f complexes are a convenient object to investigate the process of Cyt b559 photoreduction: biphasic reduction of cytochrome b559 by plastoquinol in photosystem II membrane fragments, two types of cytochrome b559/plastoquinone redox equilibria, detailed overview. In samples of PS II membrane fragments with preoxidized Cyt b559 only a fraction of Cyt b559 (about a half of photoreduced Cyt b559) can be rapidly reduced following a short illumination while the other reduced Cyt b559 is accumulated much slower in the dark. Photoreduction of Cyt b559 in the presence of decylplastoquinone Beta vulgaris ?
