Figure 6.
Figure 6 Example of a pentaiodide molecule (sites B21-B25)
binding in a partially solvent-exposed pocket formed between two
symmetry-related molecules of XI. The pentaiodide is tethered at
each end by hydrogen bonds (yellow dashes) formed with Gln234
NE2 and Lys240 NZ. The central three atoms contact through van
der Waals interactions. The symmetry-related protein molecule is
shown in green. The anomalous difference Fourier map contoured
at 4  is
shown in red mesh.
