Figure 5
CotA–ABTS interactions. Residues in close proximity to ABTS are labelled and represented as cyan stick models showing (a) the top view and (b) the side view. The 2Fo − Fc electron-density map (1σ level) around ABTS is represented in blue and the OMIT Fo − Fc map (4σ level) around ABTS is represented in red. The ABTS molecule is shown as a green stick model. |
