Figure 5. A comparison of non-bonding interactions at the
stigmatellin-binding sites of (a) the Rp. viridis RC and (b) the
S. cerevisiae cytochrome bc[1] complex. For clarity,
interactions involving the chromone head group other than
hydrogen bonding interactions (shown in light blue)^13.^ and
^14. are omitted. Labelled cyt bc[1] complex residues are from
cytochrome b with the exception of the Rieske protein residue
His181*. Interatomic distances of equal to or less than 4.0
Å involving the first half of the stigmatellin tail are
indicated in red, those with the second, terminal half, in
green. For clarity, in cases of multiple interactions fulfilling
the distance criterion for the same stigmatellin atom, only the
shortest distances are shown.
