Figure 5. The Pocket Factor, Sphingosine (Shown as a Green
Ball-and-Stick Model), in the Binding Pocket of VP1 Located
below the External Canyon Region where Host Cell Receptor
Binding OccursVP1 and VP3 are shown in blue and red ribbons,
respectively. The side chains of the surrounding amino acid
residues that have close contacts with sphingosine are shown.
The interactions between sphingosine and the amino acid residues
are primarily hydrophobic in nature (=<3.6 Å, indicated with
dashed lines). Hydrogen bonds are indicated with solid lines.
