Figure 7.
Figure 7 (a) Stereoview of the 2|F[o]| - |F[c]| electron-density map (blue) contoured at the 1 level, showing two citric acid molecules bound in the active site of Rv2074. The citrate C and O atoms are shown in grey and red, respectively. Also shown are the Na atom and coordinating water molecules. This figure was prepared by the program BOBSCRIPT (Esnouf, 1999[Esnouf, R. M. (1999). Acta Cryst. D55, 938-940.]). (b) Stereoview of the interactions between the citric acid molecules and Rv2074. The C atoms of citric acid molecules and Rv2074 are shown in grey and cyan, respectively. Hydrogen and coordination bonds are shown in green and black, respectively.
