Structure of the FAF–DSM#3 complex. (a) The FAF dimer with crystallographically equivalent DSM binding sites inside the β-barrel. The crystallographic dyad is represented by a vertical black line. (b) 2Fo − Fc electron-density map (1.5σ) around the DSM molecule in the FAF–DSM#3 complex (a difference omit map is presented in Supplementary Fig. S1). (c) Interactions stabilizing the DSM molecule inside the β-barrel: hydrogen bonds (red dashed lines) and C—H⋯π interactions (black dashed lines). (d) The shape of the binding pocket and the pose of the DSM ligand in the β-­barrel.
