A Correlation between Proton Pumping and the Bacteriorhodopsin Photocycle

In an attempt to establish a relationship between proton pumping and the photocycle intermediates of bacteriorhodopsin, we have studied the effects of pH and temperature on flash-induced proton pumping and the photointermediates O640and M412. The relative quantum yield of flash-induced proton pumpin...
