Fig. 5: Fdx-P450 docking models.

Docking models of three Fdxs in complex with PikC (a), P450sca-2 (b), and CYP-sb21 (c). The structures of P450-Fdx complexes are shown as cartoon with different colors. The key interacting residues on P450-Fdx interfaces are shown as sticks in yellow and green, respectively. Heme and substrates are shown as sticks in red and wheat, respectively. The Fe2S2 cluster are shown as spheres. The distances (Å) between the iron–sulfur cluster and heme-iron are indicated by dashed red lines.
