Models of BR, earlier M (from E204Q) and late M (from D96N) of the region that includes the retinal, Trp182, Thr178, Lys216, Ala215, Thr46, Asp96, and water molecules 501, 502, 503 and 504, shown in stereo view. Color code for the BR, and the earlier and late M states, as in Figure 3. (a) Comparison of the BR and M states of the E204Q mutant. (b) Comparison of the BR and M states of the D96N mutant.
