Abstract: | The experimental data on the absorption of plane polarized light by a solution of cattle rhodopsin at –196 C have been theoretically analysed to model the directional absorption properties of rhodopsin and prelumirhodopsin. It has been found that rhodopsin and prelumirhodopsin are planar absorbers having ratios of about 100 7 and 100 4, respectively, between the extinction coefficients along the long axis and perpendicular to it. These results support that the chromophore in prelumirhodopsin is more linear than the chromophore in rhodopsin.Work partially supported by Department of Science and Technology (India)Associated with the Biochemistry Cell |
