Figure 4.
The tetrahedral cobalt coordination-facilitated crystal contacts. The figure shows a stereoview of the SAD electron density (following density modification with DM and RESOLVE) at 2.0 A resolution contoured at 1.0[sigma] (black) and the anomalous map contoured at 5.0[sigma] (magenta); superimposed is the refined model of AvrL567-A shown in stick representation. Cobalt is shown as a green sphere and C atoms from the symmetry-related molecule are shown in green, otherwise they are shown in light blue; N, O and S atoms are shown in dark blue, red and yellow, respectively. The imidazole molecule at the top comes from the crystallization solution. Acta Crystallogr Sect F Struct Biol Cryst Commun. 2007 March 1; 63(Pt 3): 209–213.
