(a) Superimposition of the BLUF domain of the cryo-MX synchrotron structures of WT OaPAC (yellow; PDB entry 9f1y) and Y6W OaPAC (orange; PDB entry 9f1z). Distances (in Å) are shown for the cryo-MX synchrotron structure of OaPAC. (b) Flavin active site of Y6W OaPAC in the Y6W OaPAC cryo-MX synchrotron structure showing amino-acid residues participating in the hydrogen-bond network. 2mFo − DFc maps are represented as blue (flavin) and purple (residues) meshes at a contour level of 1.0σ. (c) Flavin active site of WT OaPAC in the WT OaPAC cryo-MX synchrotron structure showing amino-acid residues participating in the hydrogen-bond network. 2mFo − DFc maps are represented as blue (flavin) and purple (residues) meshes at a contour level of 1.0σ.
