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

Molecular biology and evolution - 1 Jan 1995

Yokoyama S

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 different VPs. A total of 55 amino acid changes are shown to correlate with the directions of lambda max shift and might have...
