Photoisomerization in Rhodopsin
This article reviews the primary reaction processes in rhodopsin, a photoreceptive pigment for twilight vision. Rhodopsin has an 11-cis retinal as the chromophore, which binds covalently with a lysine residue thr...

Visual pigment: G-protein-coupled receptor for light signals
The visual pigment present in photoreceptor cells is a prototypical G-protein-coupled receptor (GPCR) that receives a light signal from the outer environment using a light-absorbing chromophore, 11-cis-retinal. ...

Localization of iodopsin and rod-opsin immunoreactivity in the retina and pineal complex of the river lamprey, Lampetra japonica
The aim of this study has been to examine whether iodopsin immunoreaction exists in the photoreceptor cells of the retina of the river lamprey, Lampetra japonica, and whether this immunoreaction also appears in t...

Low Temperature FTIR Studies on the Photointermediates L, M, and N of Bacteriorhodopsin
Light-dependent changes around the protonated Schiff base of bacteriorhodopsin were studied by low temperature FTIR spectroscopy on intermediates K, L, M and N. A special effort was done for the recording of the ...

First Observation of the Formation Process of Squid Hypsorhodopsin by Picosecond Spectroscopy
Ever since hypsorhodopsin was discovered by irradiating cattle rhodopsin at liquid helium temperature [1,2], it has been a key problem in the photochemistry of vision to investigate whether the first photoprod...
