Figure 4
(a) S1-state structure superposed with the omit map for W601, W665 and W719 calculated from the dark1 dataset contoured at +5.0σ (green) and −5.0σ (orange). (b) Positive peak heights of the omit map determined for the water molecules. W719 is a well defined water molecule that does not change its structure during the S-state cycle, thus its positive omit density was used as a baseline. The figure shows relative heights of omit maps of water molecules based on that of W719.
