Figure 1
Structures of CDK kinase from G. lamblia. The apo structure (a) and the AMP-bound structure (b) are very similar. In (b) the OMIT Fo − Fc electron density for AMP is shown in green, contoured at 3.0σ. A close up of the OMIT density for AMP is shown in stereo representation in (c). The σA-weighted electron-density maps are contoured at 1σ for the 2Fo − Fc map (blue, carved with a 2 Å radius around the AMP molecule) and at ±3σ for the Fo − Fc maps (green/red, carved with a 4 Å radius around the AMP molecule). |
