FIGURE 7.

Stereoview of the carboxypalmitoyl group in its dedicated tunnel in AT52. Residues delineating the tunnel are represented as sticks and labeled. Atoms found within 5 Å of the ligand are shown as enlarged sticks and were used to depict the tunnel surface, shown as the gray semitransparent surface. Protein (respectively ligand) atoms found within 3.5 Å distances of ligand (respectively protein) atoms are colored violet. The second incomplete conformation of the carboxypalmitoyl group and its chemical environment are also depicted using the same representation scheme.
