FIGURE 5.

Structural basis of LHVS inhibition. A, surface representation of the TgCPL active site cleft with modeled LHVS shown as balls and sticks. The catalytic triad is colored magenta, and the view is the same as that depicted in Fig. 4, B and C. B, stereoview of the LHVS binding mode. The surface of TgCPL has been removed, and amino acids within 5 Å of modeled LHVS are shown as sticks, with hydrogen bonds between the enzyme and the inhibitor shown as dashed lines. C, two-dimensional representation of the LHVS binding mode. LHVS is shown as black lines, whereas the TgCPL amino acids that surround it are shown as gray lines. Hydrogen bonds are shown as dashed lines. (C was created with ChemDraw 11.)
