Figure 4
Tightly bound interface between the γ- and α-subunits. The highly hydrophobic C-terminal tail of the γ-subunit (colored green) including Cys152 of the γ-subunit covers the contact areas like a lid at the interface. The disulfide bond between subunits is indicated by a red circle. One of the long loops of the α-subunit including α2 is colored cyan and contacts the C-terminal loop region of the γ-subunit. The other colors are the same as in Fig. 2[link]. α4 and α5 of the γ-subunit also make contacts with protruding helices (α11 and α12) of the α-subunit in the area indicated with a blue circle.
