Figure 5. α-Subunit glycosylation and interaction with key residues.

(a) Top-down view of the glycosylation pocket parallel to the membrane. The α and α* subunits are colored in salmon, the β and β* subunits are in lime and the γ subunit is in marine. Glycosylation from the α/α* and β/β* subunits are shown in green and salmon sticks. Interacting residues from the γ subunit are depicted in stick representation (marine). (b) Enlarged view of the glycosylation pocket indicated by the dash-outlined frame in (a). The β and β* subunits are removed for clarity. (c) Side view of the glycosylation pocket perpendicular to the membrane. The β* subunit was removed for clarity. (d) Enlarged view of the glycosylation pocket from the dash-outlined frame in (c). The β and β* subunits were removed for clarity.
