Figure 2.
The PD-1/PD-L1 interface. Shown is a stereoview of the
PD-1/PD-L1 interface showing side chains of residues on
β-strands (CC′FG) of PD-1 (red) and on β-strands (GFCC′,
left to right) of PD-L1 (blue) that make contacts. Interacting
PD-1 side chains (pink) and PD-L1 (light blue) are shown; for
clarity a few side chains are not shown. Dotted lines (yellow)
indicate hydrogen bonds formed in the interface and with a water
molecule.
