Red-green color vision in primates is unique in the sense that it is mediated by two photoreceptor cells that are indistinguishable in all aspects except for their visual pigments. In order to...
Constraints of Opsin Structure on the Ligand-binding Site: Studies with Ring-fused Retinals¶ (2002)
Takahiro Hirano, In Taek Lim, Don Moon Kim, Xiang-Guo Zheng, Kazuo Yoshihara, Yoshiaki Oyama, ...
Ring-fused retinal analogs were designed to examine the hula-twist mode of the photoisomerization of the 9-cis retinylidene chromophore. Two 9-cis retinal analogs, the C11–C13 five-membered...

Retinochrome is a member of the rhodopsin family having a chromophore retinal and functioning as a retinal photoisomerase in squid photoreceptor cells. Unlike vertebrate rhodopsins, but like many...
Single amino acid residue as a functional determinant of rod and cone visual pigments
Imai, Hiroo, Kojima, Daisuke, Oura, Tomonori, Tachibanaki, Shuji, Terakita, Akihisa, Shichida, Yoshinori
The visual transduction processes in rod and cone photoreceptor cells begin with photon absorption by the different types of visual pigments. Cone visual pigments exhibit faster regeneration from...
Tight Asp-85–Thr-89 association during the pump switch of bacteriorhodopsin
Kandori, Hideki, Yamazaki, Yoichi, Shichida, Yoshinori, Raap, Jan, Lugtenburg, Johan, Belenky, Marina, ...
Unidirectional proton transport in bacteriorhodopsin is enforced by the switching machinery of the active site. Threonine 89 is located in this region, with its O—H group forming a hydrogen bond...
Functional role of internal water molecules in rhodopsin revealed by x-ray crystallography
Okada, Tetsuji, Fujiyoshi, Yoshinori, Silow, Maria, Navarro, Javier, Landau, Ehud M., Shichida, Yoshinori
Activation of G protein-coupled receptors (GPCRs) is triggered and regulated by structural rearrangement of the transmembrane heptahelical bundle containing a number of highly conserved residues. In...
Bistable UV pigment in the lamprey pineal
Koyanagi, Mitsumasa, Kawano, Emi, Kinugawa, Yoshimi, Oishi, Tadashi, Shichida, Yoshinori, Tamotsu, Satoshi, ...
Lower vertebrates can detect UV light with the pineal complex independently of eyes. Electrophysiological studies, together with chromophore extraction analysis, have suggested that the underlying...
Sugawara, Tohru, Terai, Yohey, Imai, Hiroo, Turner, George F., Koblmüller, Stephan, Sturmbauer, Christian, ...
Many examples of the appearance of similar traits in different lineages are known during the evolution of organisms. However, the underlying genetic mechanisms have been elucidated in very few cases....
A rhodopsin exhibiting binding ability to agonist all-trans-retinal
Tsukamoto, Hisao, Terakita, Akihisa, Shichida, Yoshinori
Rhodopsins are the members of the family of G protein-coupled receptors that have diverged from ligand-binding receptors into photoreceptive pigments. Vertebrate rhodopsins are able to bind the...
