Figure 2
The His15 binding site for platinum with Br atoms as labelled assigned as bound to Pt in the trans conformation owing to the presence of anomalous difference electron density. We have placed atoms where we are confident of their assignment, namely the histidine, the bromines and the platinums. At the extreme left the density is less easily interpretable. (a) The Cu Kα data set and (b) the I04 data set from Diamond. The 2FoFc map (blue) is shown at the 1.5 r.m.s. contour level and the anomalous difference electron-density map (orange) is shown at the 3σ contour level. The Pt atoms are shown in grey, the Br atoms are shown in yellow, C atoms are in green, O atoms are in red and N atoms are in blue.
