Fig. 3: Comparison between SAXS/WAXS merged data and calculated patterns based on molecular models.

a Data relative to the equilibrium complex formed by IsdB and metHb (closed symbols) vs. the 2IsdB:metHbdim calculated pattern obtained with CRYSOL (solid line). b Data relative to the equilibrium complex formed by IsdB and oxyHb (closed symbols) vs. the linear combination of the 2IsdB:βoxyHbtet pattern and two isolated IsdB molecules obtained with OLIGOMER (solid line, see “Methods”). Schematic representations of the molecular models used are shown in each panel. Error bars (s.e.m., n = 10) on experimental points are smaller than the symbol size.
