Figure 3
Ribbon model of HSV1 Rep showing the secondary-structure organization (left) consisting of β1, α1, β2, β3, α2, β4 and α3, and the orientation of the catalytic HUQ and tyrosine (Y81F in our model) motif (right). In our noncoordinated structure, the noncoordinating amino acid `U' is oriented away from the binding site and is therefore not shown here. |
