Figure 2.
Figure 2 (a) and (b) Na132 and (c) and (d) Na133 in the hexagonal HEWL crystal form. The twofold symmetry axes are indicated. The distances between sodium and connected O atoms are shown in (b) and (d), respectively. (2F[o] - F[c]) maps contoured at 1.0 . Distances are given in Å. Figures were generated using MOLSCRIPT v2.1.2 (Kraulis, 1991[Kraulis, P. J. (1991). J. Appl. Cryst. 24, 946-950.]), BOBSCRIPT (Esnouf, 1997[Esnouf, R. M. (1997). J. Mol. Graph. 15, 132-134.]) and RASTER3D v2.7b (Merritt & Bacon, 1997[Merritt, E. A. & Bacon, D. J. (1997). Methods Enzymol. 277, 505-524.]).
