The counterion–retinylidene Schiff base interaction of an invertebrate rhodopsin rearranges upon light activation
Animals sense light using photosensitive proteins—rhodopsins—containing a chromophore—retinal—that intrinsically absorbs in the ultraviolet. Visible light-sensitivity depends primarily on protonation of the retinylidene Schiff base (SB), which requires a negatively-charged amino acid residue—counter...
