Spectroscopic properties of MqnC. (A) UV-Vis absorbance of purified Fe/S-reconstituted MqnC (160 µM) in 100 mM phosphate buffer, pH 7.5 before (blue) and after (red) exposure to oxygen. (B) EPR spectra of purified Fe/S-reconstituted MqnC (280 µM) treated with (red and green) or without (blue) dithionite.
