H/D exchange difference map of green opsin in the dark and bleached states. The percent deuteration of the dark state was subtracted from the percent deuteration of the bleached state and displayed on the surface of the receptor. Positive differences in percent deuteration between states [Δ%deuteration (dark–bleached)] are color-coded as follows: blue for 0–4%, violet for 5–9%, and pink for 10–14%. Negative differences of percent deuteration are color coded as follows: cyan for 0–4%, green for 5–9%, yellow for 10-14%, orange for 15–19%, and red for 20–24%. Undefined regions are colored gray. Panels A–D represent side views of the green pigment, and panels E and F show top and bottom views, respectively.
