a, Guinier analysis of the scattering profiles of reduced (left, grey) and oxidized (right, pink) FeSII (30 μM) and the associated residual plots. b, Log-scale plots of the experimental scattering curves of reduced (left) and oxidized (right) FeSII compared to CRYSOL-generated theoretical scattering curves of the FeSII crystallographic structure (PDB ID: 6YAV) in the closed state (magenta), proposed open/domain-swapped state (yellow), and the FeSII cryoEM structure (blue) from this work. c, Kratky plots of reduced (left, grey) and oxidized (right, pink) FeSII each compared to the theoretical scattering profiles of the FeSII crystal structure (PDB ID: 6YAV) in the closed state (magenta), proposed open/domain-swapped state (yellow), and the FeSII cryoEM structure (blue) from this work.
