Abstract

The effects of detergents (Triton X-100) and solvents (diethyl ether, metanol) on the reversible light-induced proton uptake, photophosphorylation and band shift of the carotenoid in chromatophores from R. rubrum are described. All these compounds were found to stimulate the extent of light-induced proton uptake with subsequent inhibition when the concentrations were increased. Stimulation of proton uptake is accompanied by inhibition of both phosphorylation and carotenoid absorbance shift.
