Figure 4: Spectra and refined high-resolution structures for the five oxidation states of horseradish peroxidase. Accession codes are shown. The structures were captured at high concentrations in individual experiments (Methods) and were obtained from the first few degrees of data (Table 2 of the Supplementary Information). a, Ferric enzyme. b, Ferrous enzyme. c, Compound III (Fe -O bond distance, 1.8 Å). d, Compound I (Fe -O bond distance, 1.7 Å). e, Compound II (Fe -O bond distance, 1.8 Å).
