Аннотация

A paramagnetic Cys4[Fe] center was detected by pulse EPR in Na+-translocating NADH:quinone-oxidoreductase (Na+-NQR) by influence of this center on transverse and longitudinal spin relaxation of Na+-NQR flavin radicals. The oxidation state of the Cys4[Fe] center was Fe3+ in the oxidized and Fe2+ in the reduced Na+-NQR, as deduced from the temperature dependence of spin relaxation rates of different flavin radicals. A high-spin state of iron in the Cys4[Fe] center was assigned to both forms of Na+-NQR.
