Figure 2.

The ribbon diagram of metal-deficient (20% occupancy of Zn) hSOD1 (PDB: 1HL4) shows that Trp32 is highly solvent accessible while Val118 is shielded by the copper-binding site. Peptide 123–143 (the electrostatic loop is regarded as 121–144) is highlighted in blue. Trp32 and Val118 are shown in orange, and the copper ligands are shown in magenta. The graphic was generated using PyMOL software.
