Figure 5
Polder omit maps of the bound HPPU ligand in all chains of the asymmetric unit. Polder omit electron-density maps (blue mesh), contoured at 5.0σ, are shown for HPPU in chains A–F of the asymmetric unit in (a)–(f), respectively. HPPU is shown as an orange stick model and the Mb-P′ backbone as a green ribbon. The clear density features allow unambiguous assignment of the ligand orientation in each chain.
