Abstract The binuclear iron sulfur clusters S-1 and S-2 in all succinate dehydrogenase preparations are spin coupled, which is reflected in the saturation behavior of S-1 signal in the presence of S-2 spins and in lineshape modification of dithionite reduced enzymes at low temperatures. An additional EPR signal has been detected at approximately half the applied field of the ‘g=1.94’ signal corresponding to ‘ΔMs=2’ transition. A similar signal has been observed in Complex I preparations: one of… CONTINUE READING
