Figure 3.

X-band EPR spectra at 20 K of 0.4 mM Fe(III)ADO incubated with a 10-fold excess (4 mM) of cyanide in the absence of substrate (A) and in the presence of a 15-fold excess (6 mM) of 2-AET (B), a 5-fold (2 mM) excess of 3-MPA (C), or a 10-fold excess (4 mM) of Cys (D). g values are provided for the S = 1/2 species. The hyperfine structure in the 3000–3700 cm−1 Gauss region is due to a minor Mn(II) impurity.
