文摘The effects of cholate on the structure of bacteriorhodopsin (bR) in the purple membrane and the effects of alkali on native and cholate treated bR were studied using absorption spectra, fluorescence spectra and CD spectra. Treatment mass fraction of 10% cholate at room temperature for 48 h had no obvious effect on the structure of bR, yet changed the composition of the purple membrane, making cholate treated bR more stable in alkaline solution than native bR.
