Amino acid replacements and wavelength absorption of visual pigments in vertebrates.

Molecular biology and evolution - 1 Jan 1995

Abstract excerpt

An important unanswered question in phototransduction is how visual pigments (VPs) regulate their wavelength of maximal absorption (lambda max). By constructing the evolutionary tree for 28 opsins with known lambda max values, we can identify the times and directions of lambda max shift of differ...
