FIGURE 2.

Detailed view of vibriobactin pocket of ViuP. Ligand atoms are shown in green (carbon), red (oxygen), blue (nitrogen), and as a red sphere (iron). A, 2Fo − Fc electron density map calculated at 1.45 Å resolution (contour level of 1.5) for ferric vibriobactin and the three water molecules (salmon). The electron density map shows that Arg-244 and Arg-297 form hydrogen bonds with vibriobactin. B, illustration of the side chains of other residues that compose the binding pocket. Carbons are in light blue. C, electrostatic surface model of the binding pocket.
