Figure 4.
Fig. 4. . Schematic diagrams showing the intermolecular
interactions between PETT inhibitors (in red) and the
surrounding residues of HIV-1 RT for (a) PETT-1 and (b) PETT-2.
Residues that contact the NNRTI with a minimum inter-atomic
distance of  3.6 Å
are shown in green, whereas other residues lining the binding
pocket are shown in blue. The individual distances between the
NNRTI and the protein atoms are shown as dashed lines (distances
3.3 Å
in pink, 3.3 Å < distances 3.6 Å
in light blue). Hydrogen bonds together with their distances are
shown in black.
