Magnetic interaction between Q(A)(-center dot) and the triplet state of the primary donor in modified reaction centers of the photosynthetic bacterium Rhodobacter sphaeroides R26

Abstract:

The interaction between the reduced primary acceptor quinone (Q(A)-.), and the triplet state of the primary donor 3D is investigated with time-resolved continuous-wave EPR. The trough at high-field in the Q(A)-. electron-spin polarized X-band EPR-spectrum at early delay times after the laser flash [De Groot et al. (1985) Biochim. Biophys. Acta 808, 13-20] is studied as a function of temperature and of the delay, in zinc-reconstituted reaction centers, with and without carotenoid. In all cases...
