Figure 4
Quaternary-structural transitions in the overall structure. (a) Superposition of the 24-meric assemblies of OliHb. The color schemes are the same as in Fig. 3[link]. A tetrameric subassembly is represented as a transparent surface model superposed on the overall structures, and a close-up view is shown in the right panel. The centers of gravity of each A1 and A2 subunit are represented as spheres of the same color. (b) Transition of the distance between the centers of gravity of the A1 and A2 subunits [dashed line in (a)].
