Figure 6.
Fig. 6. a, comparison of the HPV-18 E2/D protein in the free (green) and DNA-bound (gold) states. The left subunit is superimposed. b, comparison of the complexes formed by HPV-18 E2/D (gold) and BPV-1 E2/D (blue) with E2BS(AATT). The left subunit of each protein is superimposed. c, the intersubunit interactions between side chains in the [2]/ [3] loop and the C-terminal region of the recognition helix in the BPV-1 E2/D-E2BS(AATT) complex. The backbone worm representing relevant regions of the two subunits are shown in different colors.
