3-D rendering of the backbone traces of ST3Gal I, II, III, IV, V and VI superposed on each other using SwissPDBViewer. Helices A, E, F and I (all in cyan) and strands β1, β2, β4, β5, β5', β6 and β7 (all in yellow) superpose well on each other. Residues constituting these helices and strands are given in Figure 1. Loops and other helices/strands have different conformations in the six proteins and hence have been shown for only ST3Gal I (dark gray). PyMol was used for rendering.
