Figure 5. Loop VI in bovine and yeast SOD1.

Figure 5

Loop VI of bovine (A) and yeast (B) SOD1 (PDB code 1COB and 1B4L respectively) are superposed with chains A (transparent pink) and B (transparent cyan) of 2-ME-SOD1. Bonds and carbon atoms are shown as dark grey sticks and small spheres respectively, with small spheres of nitrogen (cyan) and oxygen (red) atoms. The transparency of chains A or B of 2-ME-SOD1 is less when the superposed structures are similar. Loop VI of bovine and yeast SOD1 can be also classified into H- and F-types by the existence of the hydrogen bond between 105th and 110th residues as in human SOD1. Moreover, the entire structures of loop VI of bovine and yeast SOD1 are quite similar to H- and F-types respectively.
