Figure 2.

The crystal structure of PPT1 complexed with palmitate. β3–β8 and αA, αB, αC, and αF are elements of the canonical α/β hydrolase fold and are labeled according to the nomenclature of Ollis (27). The palmitate, the catalytic triad, and the glycosylated asparagines are indicated. B is a rotation by 90° from A. Figs. 2, 3, and 5 were prepared by using bobscript (28), molscript (29), and raster3d (30).
