Figure 2. Overall structures of the OFORs in homodimer forms.

Figure 2

(a) StOFOR2. (b) StOFOR1. (c) DaPFOR. (d) MtOOR. The domains are shown in the same colors as in Fig. 1, and the other protomer is shown in gray. TPP (cyan), the [4Fe-4S] cluster (orange), and pyruvate (black) are shown as spheres. The Lys125b residues (blue sticks) in StOFOR2 (a) and StOFOR2 (b) are indicated by red circles and arrows. A black arrow indicates the second protomer of StOFOR1, whose cofactors are lost.
