[Protein carriers of the electron transport chain of non-photosynthesizing mutants of Chlamydomonas reinhardii].
The amounts of ferredoxin, plastocyanin, ferredoxin-NADP-reductase were determined by electrophoresis and differential spectroscopy. The cytochrome levels in the chloroplasts of non-photosynthesizing mutants Chlamydomonas reinhardii were determined both in active and inactive photosystems. It was shown that the loss of PS-1 activity did not affect the amount and activity of the electron carriers. The disturbances of the donor side of PS-2 in the mutants were accompanied by a loss of the reaction center activity and by a decrease of cytochrome b599. The amounts of other protein components in the mutants with inactive PS-2 remained unchanged. The disturbances in the cytochrome c553 content presumably blocked the electron transfer between the photosystems but did not affect the activity of the reaction centers of PS and the levels of other carriers of the chloroplast electron transport chain.
