Structures of mitochondrial ubihydroquinone:cytochrome c oxidoreductase (bc(1) complex) from several animal sources have provided a basis for understanding the functional mechanism at the molecular(More)
In the Rieske iron-sulfur protein (ISP) of the ubiquinol:cytochrome c(2) oxidoreductase (bc(1) complex) of Rhodobacter sphaeroides, residue Tyr 156 is located close to the iron-sulfur cluster.(More)
In photosystem I, oxidation of reduced acceptor A(1)(-) through iron-sulfur cluster F(X) is biphasic with half-times of approximately 5-30 ns ("fast" phase) and approximately 150-300 ns ("slow"(More)
The directionality of electron transfer in Photosystem I (PS I) is investigated using site-directed mutations in the phylloquinone (QK) and FX binding regions of Synnechocystis sp. PCC 6803. The(More)
