EPR properties of the FeVco-reconstituted ΔnifB MoFe protein (black trace), the wild-type VFe protein (red trace), the FeMoco-reconstituted ΔnifB MoFe protein (green trace), and the wild-type MoFe protein (blue trace). Samples containing the FeVco were measured at 6 K, whereas those containing the FeMoco were measured at 15 K. The power and temperature at which the spectra were taken were determined on the basis of power- and temperature-dependent experiments, where the spectra were saturated in intensity and optimized for line-width. The (apparent) g values are indicated. All samples contained equimolar V or Mo.
