Figure 2.
Interactions of the Z-S5S4K3L2(boro)L1 inhibitor with the key residues in the catalytic pocket.
Catalytic triad residues are shown in yellow, the protease residues in magenta and the backbone of 204–206 residues in green. Dotted lines represent hydrogen bonds, and the dotted circle pinpoints the exact location of the boronic acid moiety.
