Figure 4 FAD Cofactor and its Protein Environment
Shown are the residues involved in hydrogen bonds (depicted by dashed lines) and hydrophobic interactions with the flavin ligand. The figure was generated using the program LIGPLOT+ (Laskowski and Swindells, 2011). Structure , DOI: ( /j.str ) Copyright © 2015 Elsevier Ltd Terms and Conditions

Figure 5 Electron Density Surrounding the FAD Cofactor
(A and B) Model of the FAD cofactor shown from the top (A) and side (B). The 2Fo − Fc electron density map drawn at a σ level of 1.0 is shown as a mesh. (C and D) Overlays of a planar (red) and the observed butterfly (green) conformation shown from the top (C) and side (D). The electron density map is displayed in the same way as in (A) and (B).
