Abstract:

The goal of this review is to consider recent experimental data concerning a new parameter of prokaryotic membranes—the electrochemical protons gradient (ΔμH+) predicted by Mitchell (1966)—in the case of photophosphorylating bacteria. Along with the data on bacteriochlorophyll-containing bacteria, we have included information about the extreme halophilic bacterium Halobacterium halobium, because recent experimental data allow its consideration as a photophosphorylating organism. A special section will be devoted to data about the structure of the most interesting molecular generator of ΔμH+, bacteriorhodopsin. In the final part of the chapter we intend to discuss membrane potential functions in more general terms, and do not restrict the experimental basis of discussion to photophosphorylating membranes only.
