Figure 5. Ribbon diagram of the TC14 dimer. All elements of secondary structure are labelled in the upper molecule, and labelling is repeated for some elements in the lower molecule to improve clarity. The sugar-binding calcium ions are shown as grey spheres and the galactose molecules in a ball-and-stick representation.
