Figure 7. Figure 7. A best-fit superposition of the free PurR DBD structure onto the ternary complex structure of the PurR–hypoxanthine–purF-operator. The backbone atoms of the free PurR DBD (Met1–Ser48) are shown in yellow, and the backbone atoms of PurR dimer in the ternary complex are shown in blue and red, the two colours distinguishing the two monomers. The DNA atoms are shown in pink and white. Two hypoxanthine molecules bound to PurR dimer are also shown in white. Figure 7.
