Superposition of the FAD-binding site of FdR9 (PDB entry 6tuk, gray) with the structures of other ferredoxin reductases [PDB entries 3fg2 (PuR), 3lxd (ArR), 2gqw (BphA4) and 1q1w (PdR)]. Residues forming hydrogen-bond interactions with the FAD cofactor are shown as sticks. Hydrogen bonds are indicated by dotted lines. |
