RIESKE SOLUBLE FRAGMENT FROM SPINACH
Overview
BACKGROUND: The cytochrome b6f complex functions in oxygenic, photosynthesis as an integral membrane protein complex that mediates, coupled electron transfer and proton translocation. The Rieske [2Fe-2S], protein subunit of the complex functions at the electropositive (p), membrane interface as the electron acceptor for plastoquinol and donor for, the cytochrome f subunit, and may have a dynamic role in catalyzing, electron and proton transfer at the membrane interface. There are, significant structure/function similarities to the cytochrome bc1 complex, of the respiratory chain. RESULTS: The 1.83 A crystal structure of a, 139-residue C-terminal fragment of the Rieske [2Fe-2S] protein, derived, from the cytochrome b6f complex of spinach chloroplasts, has been solved, by multiwavelength ...
