FAD-binding site in MnmC1 domain. A) Omit electron density map (Fo-Fc; contoured at σ=3.0) around FAD in ecMnmC. B) Schematic diagram showing hydrogen bond interactions of FAD within the active site of ecMnmC within 3.2 Å. Numbers represent distance in Å C) Stereo view of the surface representation around ecMnmC1 active site with bound FAD displayed in sticks. Green sphere represents a chloride ion.
