Three Amino Acids Tune Red Against Green
Macaque cone-pigment structures found three substitutions account for nearly the full spectral shift between red and green sensitivity.
Summary
Macaque cone-pigment structures found three substitutions account for nearly the full spectral shift between red and green sensitivity.
The Science study ties the shift mainly to electrostatic changes around the shared retinal molecule and identifies a membrane-facing opening that may aid fast pigment regeneration. Macaque pigments closely resemble human ones, but the structural result is not a treatment for color-vision deficiency.
Why it matters
Macaque cone-pigment structures found three substitutions account for nearly the full spectral shift between red and green sensitivity.
Limits and context
- Macaque pigments closely resemble human ones, but the structural result is not a treatment for color-vision deficiency.
Key claims
