Figure 2

Metal binding sites with 2Fo-Fc electron density (blue) contoured at 1σ around metal and ligands. One monomer is in magenta and the other in green. (a) Ni2+-MBD, (b) Cu2+-MBD, (c) Zn2+-MBD. The dispersive difference map (orange) was calculated by subtracting data collected at 1.2829 Å (zinc inflection wavelength) from 1.00 Å (a remote wavelength) and indicates the presence of zinc, contoured at −8.0 σ. (d) Zn2+-MBD with Fo-Fc difference density maps around the zinc binding sites with positive difference electron density in green contoured at +3σ and negative difference electron density in red contoured at −3σ.
