Figure 4From: Crystal structure of Escherichia coli protein ybgI, a toroidal structure with a dinuclear metal siteA view looking down into the toroid at the putative active site. A gap between the dimers and a trough lead down toward the site. Where conserved residues contact the surface, the surface has been colored red. Again the metal ions are depicted as silver balls. This figure was prepared using PyMol [34].Back to article page
