Figure 10
The active site and Zn2+ coordination in BcCCP. Selected residues in the active site and acetate are displayed and coloured as follows: C, white (yellow for acetate); O, red; N, blue. The 2Fo − Fc electron-density map is shown for acetate, where Fo represents the observed structure factors and Fc represents the calculated structure factors. The map is depicted at the 1σ level (cyan chicken wire). The cation and a water ligand are shown as spheres coloured grey and marine, respectively. Zinc coordination is shown by black continuous lines; blue dashed lines represent hydrogen-bonding interactions. |
