Figure 4.
Illustrative models of different turn conformations for hairpin polyamides containing the (R)-α-amino-γ-turn (A and B), (S)-β-amino-γ-turn (C and D), and the (R)-β-amino-γ-turn (E and F) bound to the minor groove of DNA (dark gray = carbons, white = hydrogen, blue = nitrogen, red = oxygen).
