Origin and evolution of retinoid isomerization machinery in vertebrate visual cycle: hint from jawless vertebrates.
In order to maintain visual sensitivity at all light levels, the vertebrate eye possesses a mechanism to regenerate the visual pigment chromophore 11-cis retinal in the dark enzymatically, unlike in all other taxa, which rely on photoisomerization. This mechanism is termed the visual cycle and is lo...
