ESEEM and ENDOR studies of the Rieske iron-sulphur protein in bovine heart mitochondrial membranes.

Electron nuclear double resonance (ENDOR) and electron spin echo envelope modulation (ESEEM) were applied to the respiratory-chain iron-sulphur clusters in natural bovine heart mitochondrial membranes. By using specific reduction, signals were observed from the Complex III Rieske [2Fe-2S] cluster. In ENDOR, 1H hyperfine couplings in the range 0.5-7 MHz were… CONTINUE READING
