FIGURE 8.

Structure of C-terminal domains and caddie protein. A, structure of the C-terminal domain of melB holo-pro-tyrosinase. B, structure of the shielding domain of the functional unit of Octopus hemocyanin (PDB code 1JS8). C, structure of the caddie protein of S. castaneoglobisporus tyrosinase (PDB code 1WX2). D, superimposed structure of the C-terminal domain of melB (red) versus shielding domain of octopus hemocyanin (PDB code 1JS8) (yellow). The dotted line indicates the residues not visible in the electron density.
