Figure 2
Anomalous electron-density map in the asymmetric unit contoured at 3.5σ in red, calculated using PHASER phases combined with the anomalous difference of the Bijvoet pairs of the data set measured at the absorption peak of As. The model shown is MOP. The Mo active site and the two [2Fe–2S] clusters are shown as ball-and-stick representations and appear sequentially from the middle of the picture to the bottom left. |
