EPR properties of ΔnifB NifEN (red), NifENPrecursor (blue) and NifEN“FeMoco”(20 mM) (green) in dithionite-reduced (A) and IDS-oxidized (B) states. The dithionite-reduced samples were measured at 6 K, whereas the IDS-oxidized samples were measured at 15 K. The features of NifEN“FeMoco”(20 mM) are enlarged, and the g values are indicated.
