- W2000943250 abstract "Abstract The photochemical oxidation and reduction of P -700 were studied in digitonin- and in sodium dodecyl sulphate (SDS)-Photosystem I (PS I) particles in the presence of ascorbate. In digitonin-PS I particles, reduction of P -700 + occurs by the bound iron-sulphur protein ( P -430) and by ascorbate. The relative contribution of these back reactions depends on the length of the exposure to light and on the temperature and pH of the reaction medium. Experiments performed under anaerobic conditions demonstrate that some endogenous component may serve as the electron acceptor of P -430 − . The rate of the latter reaction is also dependent upon the temperature and pH of the sample. At pH 9 and lower temperatures the rate of this reaction is so much reduced that the reduction of P -700 + by ascorbate, which increases rapidly at high pH, can be observed even during illumination. The effects of secondary electron acceptors and of the presence of SDS on the absorption changes due to P -700 are also reported. Low concentrations of SDS are shown to retard the back reaction of P -700 + with P -430 − . Studies with SDS-PS I particles (CP I ) confirm the absence of the iron-sulphur centres in this preparation. Three larger P -700-chlorophyll a -protein complexes prepared by mild electrophoresis in the presence of SDS plus Triton X-100, however, still contain P -430." @default.
