Figure 3 Analysis of the concave surface of Cvx. (a) Surface representation of the Cvx tetramer. (b) Orientation of the concave surface relative to the rest of the molecule. - and -subunits are coloured blue and red, respectively. The van der Waals surface of the -heterodimer is depicted in transparent grey and the concave surface with a transparent brown tint. Relative orientations of views are given. (c) Close-up view of the concave surface of the -heterodimer. Residues contributing to charged patches are indicated. (d) Schematic representation of the Cvx tetramer interaction with protein ligand at the cell surface. The Cvx tetramer is depicted as in Fig. 1-(a) with a 120° rotation about the horizontal. Ligand molecules interacting at each concave surface are depicted as transparent gold spheres. The cell surface is depicted in grey.
