Figure 3. Stereo view of the xenon-binding cavity in MBP.
The electron density in cyan corresponds to a 2F[obs] -F[calc]
map contoured at 2s. The xenon is localized in the cavity away
from the lysine and water that mark the end of the cavity at the
protein surface. While the presence of many hydrophobic
side-chains is often observed in xenon-binding cavities, the
proximity of the cavity to the surface is less common.
