Figure 1
The SFX structure of S. lividans DtpB. (a) The ferric DtpB hexamer shown in cartoon representation possesses D3 dihedral symmetry with the rotation axis indicated. Each of the six chains (A–F) is colour-coded: A, navy blue; B, grey; C, teal; D, mint green; E, coral; F, lavender. The heme group in each chain is shown in blue sticks. (b) The active-site heme of chain A in the pentacoordinate ferric, Fe(III), state and the H2O2-reacted [Fe(IV)=O] Compound I state. 2Fo − Fc electron-density maps are contoured at 1.5σ (blue mesh) with heme and the proximal His ligand shown in sticks. The modelled O atom is shown as a red sphere with bond length indicated. [PDB entries 6yrj (ferric) and 6yrd (Compound I).] |
