Figure 3. Difference omit maps of (a) the LiPH8-H[2]O[2]structure and (b) the pristine LiPH8 structure for residue Trp171 at 1.73 and 1.8 Å resolution, respectively. The maps in cyan are (2F[o] -F[c])exp(ia[c]) electron densities contoured at 2 s where all atoms of Trp171 were omitted for phase calculation. In red a (F[o] -F[c])exp(ia[c]) electron density map is shown, contoured at 8 s where only the hydroxy group was omitted. The picture was produced with O [Jones et al 1991].
