Figure 3. Residues 87–93 Pack Identically into
Symmetry-Related HLA Binding Sites
The gp42 N-terminal
residues that are immediately proximal to the CTLD extend
similarly in the two copies of the gp42 molecules in the
asymmetric unit and make identical packing interactions with the
HLA binding site of a neighboring molecule.
(A) The overlay
of the two gp42 molecules of the asymmetric unit is shown in
beige, with the N-terminal residues in yellow stick
representation that form this packing interaction with the
neighboring gp42 (blue). The HLA binding site is indicated and
the corresponding residues are shown as sticks.
(B) A
zoomed-in view of this packing interaction is shown, along with
the packing of residue F88 against hydrophobic HLA binding
residues.
