Figure 3.

Spontaneously formed [4Fe–4S] cluster nests with S … S distances (in Å) for the CIACGAC FdM-FdM-7-C peptide as indicated by brown vertical bars at the bottom of the secondary structure analysis plots in figure 2b. The nest lifetimes for frames #7138, #12250 and #37177 are 1 ps. However, #44586 is part of a block of frames that last for close to 270 ps (see also on page 9 of electronic supplementary material).
