EPR spectra of WT (A) and Y294K (B) MauG. The low-spin ferric species in the spectrum of WT MauG, which corresponds to the His-Tyr ligated heme, is labeled for clarification. Samples containing 150 μM WT or Y294K MauG were prepared in 50 mM potassium phosphate buffer, pH 7.4. Spectra were obtained at 10 K with microwave frequency, 9.65 GHz, microwave power, 1 mW, and modulation magnitude, 0.5 mT.
