Figure 5.
FIGURE 5. Electron density maps of apo- and heme-bound HO-2. A, stereo view of the F[o] - F[c] map of the heme-bound HO-2 heme pocket contoured at 3 . The heme group is shown with carbon in gray, oxygen in red, and iron in orange. The red spheres represent water molecules. B, stereo view of the 2 F[o] - F[c] of the hydrophobic region in the heme pocket of apoHO-2 shown at 1 . The Triton X-100 is shown with carbon in yellow and oxygen in red.
