Figure 6 Relative positions of the redox centres in the two
different conformations of the bc[1] complex dimer. a, b, Iron
centres revealed by anomalous scattering near the iron edge. The
net is a Bivoet difference map with X-ray wavelength 7,131 eV
phased with experimental phases improved by averaging, and
contoured at 4.5 .
c, d, Schematic drawing representing the cofactors. a, c,
Results from a native crystal, with the iron-sulphur cluster of
the Rieske protein in the distal position (from the
low-potential haem group of cytochrome b). b, d, Results from a
crystal containing bound stigmatellin, with the cluster in the
proximal position.
