Figure 8
Crystal contacts between symmetry-related molecules in the tetragonal FOA complex of T109S DHOase. The symmetry-related molecule (y − 1/2, −x + 1/2, z − 1/4) is coloured green. The flexible loop (residues 105–115) is shown in magenta. The Zn atoms and FOA molecule are displayed in the active site. (a) shows the hydrogen bonds involved between the two molecules. (b) displays the superposition of the `loop-in' conformation from the wild-type structure (chain B from PDB code 1xge, blue) onto the tetragonal structure.
