The diiron cluster observed in the X-ray crystal structure of CmlA in its chemically reduced state (WTR). (A) Bond distances for the iron and first-sphere ligands, given in Å. (B) Electron density map of WTR. The blue mesh is the 2|Fo|-|Fc| map contoured at 1.5 σ and the green mesh is the |Fo|-|Fc| omit map for the solvent-derived ligands contoured at +4.5 σ. Atom coloring is as in Figure 1.
