Figure 3.
FIG. 3. Close up view of the DesIV active site. A close up view of the active site, within 3.2 Å of the NAD^+ and dTDP ligands, is shown in a. For the sake of clarity, Ser87 and His88 were omitted from the figure. The side chain hydroxyl group of Ser87 interacts with a phosphoryl oxygen of the NAD^+ while N 2 of His88 forms a hydrogen bond with a phosphoryl oxygen of the dTDP. A schematic of the hydrogen-bonding pattern around dTDP is displayed in b. Possible hydrogen-bonding interactions within 3.2 Å are indicated by dashed lines.
