Figure 4.
Fig. 4. Predicted and experimental ligand orientations for the polar L99A/M102Q cavity site. The carbon atoms of the crystallographic, DOCK, AMBERDOCK, and PLOP predicted poses are colored gray, yellow, cyan, and magenta, respectively. Hydrogen bonds are depicted with dashed lines. The F[o] − F[c] electron density omit maps (green mesh) are contoured at 2.5–3.0σ. (a) n-Phenylglycinonitrile (10), (b) 2-nitrothiophene (11), (c) 2-(n-propylthio)ethanol (12), (d) 3-methylbenzylazide (6), (e) 2-phenoxyethanol (9), and (f) (R)-(+)-3-chloro-1-phenyl-1-propanol (13) bound to L99A/M102Q.
