Figure 4 Electron-density maps of the various CO cavities.
Electron-density maps were made by removing residues affected by
CO photolysis and/or CO from the model and then calculating the
[A]-weighted
F[o] - F[c] maps. The labelled photolyzed residues and/or CO
were reinserted to show that their placements fit with the F[o]
- F[c] density at 3 .
The CO-bound `laser off' model is represented by the purple
coordinates, the photolyzed time points are represented by the
green coordinates and the photolyzed CO in blue. Positive
density in the F[o] - F[c] map is displayed in red and negative
density is displayed in black at 3 .
(a) shows the 100 ps F[o] - F[c] map with Phe29 and His64 from
the photolyzed model and the primary docking site CO deleted.
(b) shows the 316 ps F[o] - F[c] map with only the photolyzed
COs removed and (c) shows the 316 ns F[o] - F[c] map with the CO
removed from the proximal Xe1 site.
