Figure 2
OMIT maps for detecting electron-density peaks of metal ions at metal-binding sites A and B in the (a) 0 s, (b) 25 s, (c) 40 s, (d) 60 s and (e) 230 s structures. Only the two metal ions are omitted for calculations. HindIII and the DNA molecules are shown as stick models. Water molecules are shown as small cyan-coloured balls. Electron-density contours are shown at 6σ (cyan), 9σ (deep blue) and 12σ (purple).
