Figure 4.

A schematic diagram of protein–DNA interactions in LlaGIΔN-DNA complex. Amino acid colours are according to domains in Figure 2A. DNA bases are cyan (A), brown (T), blue (C) and yellow (G), main chain interactions are pink lines, side chain interactions are purple lines. The target adenine (green) is +1, with downstream positions defined as positive and upstream positions defined as negative. Residues Y1021, F1133, R1119 and R1138 are depicted as lavender, orange, sky blue and black coloured boxes, respectively.
