Structural comparisons of the EF-hands between EFhd1Zn and EFhd2Zn. (a) and (b) Detailed illustrated views of (a) EF1 and (b) EF2 in EFhd1Zn with Zn2+ bound. EF1 and EF2 are shown in teal. Zn2+ and water are shown as dark gray and sky blue spheres, respectively. (c) and (d) Detailed illustrated views of (c) EF1 and (d) EF2 in EFhd2Zn with Zn2+ bound. EF1 and EF2 are shown in magenta. Zn2+ and water are shown as dark gray and sky blue spheres, respectively. (e) and (f) Detailed illustrated view of superimposed (e) EF1 and (f) EF2 from EFhd1Zn and EFhd2Zn. Zn2+ is shown as teal (EFhd1) and magenta (EFhd2) spheres. Water molecules are showed as pale teal and pale magenta spheres. In all panels, the residues for Zn2+ coordination are shown in stick form, and Zn2+ coordination is represented by dashed lines.
