Figure 9
The crystal structure (PDB entry 4jdo) of the CTD + NTD fusion protein. The structure shows that the threefold axes of the CTD and the NTD are collinear; there are three molecules in the asymmetric unit in this crystal. Shown here are two of these viewed along their threefold axis (middle and right) and one perpendicular to it (extreme left). This figure was prepared with CCP4mg (McNicholas et al., 2011BB23).
