Effects of Hg(2+) ions on the absorption spectrum of bacteriorhodopsin have been measured at different pH values and after acetylation. UV-difference spectroscopy and CD spectra show that Hg(2+)-induced color change is essentially similar to that caused by removal of cations or acidification. The ability of Hg(2+)-induced purple-to-blue transition is pH… CONTINUE READING
