MCD (top) and electronic absorption (bottom) spectra of cyclohexylamine and nitrite (NO2)-bound ferric H93G Mb (0.5 M cyclohexylamine, 0.1 M NaNO2) (solid line) compared to 4-methylimidazole (4Me-Im) and nitrite (NO2)-bound ferric H93G Mb (0.1 mM 4Me-Im, 0.1 M NaNO2) (dashed line). The spectra were recorded in 0.1 M potassium phosphate at pH 7.0 at 4 °C.
