Figure 4. Examples of electron density maps revealing the
position of hydrogen atoms. The 2F[o] -F[c] electron density map
(gray) is contoured at +1.0 s, while the F[o] -F[c] difference
electron density map (red) prior to inclusion of hydrogen atoms
is contoured at +3.0 s and superimposed. A, Ile218; B, Lys203;
C, Leu258; and D, Ile247.
