Abstract excerpt
The vast diversity in spectral sensitivities in the vision of many organisms is mediated mostly (although not entirely) through variation in the photosensitive visual pigments (opsins) of the eye. Specifically, shifts in absorption maxima of visual pigments are thought to be a result of interactions within the binding pocket of the opsin, between amino acid side chains and the retinal chromophore, However, it has...
