Zinc identification in the LMO4 structure. (a) Overall fold of the LMO4 structure. The protein is depicted in cartoon representation and coloured grey. Residues with S atoms or that interact with zinc ions are shown as sticks, with sulfur, oxygen and nitrogen coloured green, red and blue, respectively. Zinc ions are represented by orange spheres. (b) Close-up view of zinc ion binding sites. Anomalous difference Fourier maps are represented as gold mesh and contoured at 4σ. Data sets collected above and below the Zn K edge are shown in the top and bottom rows, respectively. The numbers at the bottom right of each panel correspond to the anomalous peak heights (σ). |
