Figure 2
The hybrid clusters in HCP and the CoD β-subunit. (a) Model representation of the hybrid cluster in the as-isolated oxidized form of D. vulgaris HCP prepared anaerobically (this work; PDB code 1w9m ). Bonds associated with the metal cluster are shown as dotted lines, whereas metal–residue ligand interactions are drawn as full lines; only residue side chains are shown for clarity. (b) Model representation of the hybrid cluster in the D. vulgaris HCP reduced form (PDB code 1oa1 ). (c) Model representation of the C-cluster in M. thermoacetica CoD (PDB code 1mjg ). (d) Superposition of the anaerobically purified HCP hybrid cluster (bonds in blue) and CoD C-cluster (bonds in orange). The ligands binding Fe5 (Cys434), Fe6 (Cys312) and Fe8 (Cys406) in HCP are structurally identical to the ligands binding Fe4 (Cys500), Fe1 (Cys355) and Fe3 (Cys470) in the M. thermoacetica CoD C-cluster (see also Table 4 ![[link]](../../../../../../logos/arrows/d_arr.gif) and Fig. 4). Atom colouring: nickel, green; nitrogen, blue; oxygen, red; sulphur, yellow; iron brown in (a), (b) and (c) and black in (d). |
