pubmed:abstractText |
The action of dipyridamole (DIP) on dark recombination between the photooxidized special pair bacteriochlorophyll BChl2+ and reduced primary quinone acceptor Q(A)- in the reaction centres (RCs) of the bacteria Rhodobacter sphaeroides was studied in the presence of different detergents (LDAO, Triton X-100, sodium cholate, sodium dodecyl sulfate). DIP accelerated this reaction approximately 4-5-fold. In RCs with the extracted H-subunit, the effect of DIP was observed at lower concentrations. The possibility of modification of the RC structure-dynamic state by DIP (including changes in RC hydrogen bonds) is proposed. The modification obviously disturbs the processes of the long-life electrostatic stabilization of Q(A)-.
