Figure 6
Structural comparison of the NAD-binding sites of FdR9 (PDB entry 6tuk) and the reductase BphA4 (PDB entry 1f3p) in complex with NAD+. The amino-acid residues of BphA4 interacting with NAD+ and the corresponding residues in FdR9 are labeled. The loops containing the GxGxxG motif of BphA4 and the GxSxxS motif of FdR9 are shown in red. |
