Figure 3
A stereo diagram of the active site of 3,6-DKMO viewed from the solvent region. The cofactor FMN, modelled with an occupancy of 0.6, and neighbouring residues are shown as stick models. The positive OMIT Fo − Fc electron-density map contoured at 3.0σ is shown in green and the negative Fo − Fc map contoured at 3.0σ is shown in red. The OMIT difference electron density was calculated by BUSTER using a structure from which all solvent and cofactor molecules had been removed and the model refined to reduce the bias. The figure was prepared using PyMOL (DeLano, 2002). |
