Figure 3
SSO2064 subdomains display a novel spatial organization with respect to other OB-fold-containing and zinc-ribbon-containing proteins. Stereo ribbon diagram showing the structural superposition of SSO2064 (PDB code 3irb ; residues 8–144; blue) with (a) the mini-chromosome maintenance complex (MCM) from M. thermoautotrophicum (PDB code 1ltl ; residues 95–242; gray) and (b) chains A (residues 28–83; cyan) and Y (residues 10–71; magenta) from the large ribosomal subunit from H. marismortui (PDB code 1jj2 ; Klein et al., 2001

). Zinc (gray and blue) and cobalt (magenta) [chain Y in (b)] are indicated as spheres.
