FIG. 4.
EPR spectra of reduced AntAB and AntC. Purified samples of protein (250 μM) were reduced anaerobically with excess sodium dithionite (0.5 mM). Spectra were recorded under the following conditions: temperature, 10 K; microwave frequency, 9.59 GHz; modulation amplitude, 6.366 G; microwave power, 4 mW.
