Abstract

The chromophore of rhodopsin, the visual pigment, consists of 1 1-cis-retinall bound to the €-amino terminal of a lysine residue of the apoprotein opsin via a protonated Schiff base linkage.213 The 1 1 -cis-retinal protonated Schiff base formed from n-butylamine absorbs at 440 nm in methan01,~ whereas the maxima of visual pigments from various sources have ...
