Photoactivation and conformational gating for manganese binding and oxidation in bacterial reaction centers

Author(s): Samaei A; Deshmukh SS; Protheroe C; Nyéki S; Tremblay-Ethier RA; Kálmán L;

The influence of illumination history of native bacterial reaction centers (BRCs) on the ability of binding and photo-induced oxidation of manganous ions was investigated in the pH range between 8.0 and 9.4. Binding of manganous ions to a buried site required 6 to 11-fold longer incubation periods, depending on the pH, in dark-adapted BRCs than in BRCs th ...
