N-retinyl, the chromophore of bleached and reduced rhodopsin, N-retinyl-opsin, was used as a covalently attached fluorescence probe to examine the structure of N-retinyl-opsin and the rod outer segment. The efficiency of energy transfer from the protein part of N-retinyl-opsin to the chromophore is 12 +/- 5%. It is argued that this implies that the N… (More)
