[Biophysical and Biochemical Research of Animal Rhodopsins].

Abstract excerpt

Opsins (also called animal rhodopsins) are universal photoreceptive proteins that provide the molecular basis of visual and nonvisual photoreception in animals, including humans. Opsins consist of seven helical α-transmembrane domains and use retinal, a derivative of vitamin A, as a chromophore. In many opsins, light absorption triggers photo-isomerization from 11-cis retinal to all-trans retinal, resulting in...
