Figure 7.
Diagram of CD59. (a) Ribbon diagram (1). Conserved residues (Tyr36, Trp40, and Leu54) and Phe23 (always hydrophobic) which were mutated for functional studies are shown. The two fragments of the protein (1-16 and 57-77) that can be replaced with Ly6E sequence without affecting function are shown by yellow ribbon. (b) Molecular surface of CD59. The exposed surface patches of all of the evolutionary conserved residues that occur between positions 16-57 on the displayed face of the molecules are shown (green patches). Conserved residue classes are shown in blue (refer to text for details). The colored patches represent the molecular surface of the side chains of conserved residues and residue classes.
