Figure 6

Low-temperature (4.2 K) Mössbauer spectra of (A) as-isolated and (B) dithionite-reduced cyt cm552, recorded in the absence of an applied magnetic field. The bracket marks the doublet arising from a ferrous high-spin heme. The solid line is a fit composed of four species of equal amounts with parameters typical of low- and high-spin ferrous hemes.
