Figure 23.2.4.3
A comparison of the orientations of α-helices bound in the major groove, taking examples from four DNA-binding proteins: the 434 repressor (Shimon & Harrison, 1993), the engrailed homeodomain (Kissinger et al., 1990), the trp repressor (Otwinowski et al., 1988a,b) and the Zif268 zinc finger (Pavletich & Pabo, 1991). The DNA backbone is shown as a brown ribbon, whereas the protein helix is shown as a blue ribbon. |
