Figure 5.

Structures of several protease-inhibitor complexes. The structures of inhibitors in complexes with proteases are shown. NS2B and NS3 are shown in green and light blue, respectively. The PDB accessing codes are indicated in the figure. All the structures are shown in the same orientation. Several types of inhibitors such as peptidic inhibitors, fragments, irreversible inhibitors, and allosteric inhibitors are shown in sticks.
