Figure 2 The C^ tracings of the SDXyI structure: (a) monomer, the 2 helix Asp64-Thr81 of the / -barrel; the fragment Glu357-Ala364 and the metal sites are indicated, (b) `butterfly' dimer or asymmetric unit dimer, (c) `yin-yang' dimer and (d) `diagonal' dimer. The figures were rendered using MOLSCRIPT (Kraulis, 1991[Kraulis, P. J. (1991). J. Appl. Cryst. 24, 946-950.]).
