| Short Name | N_fixation_NifU |
| description | The nitrogen fixation protein NifU is required for full activation of the metalloenzyme nitrogenase, the catalytic component of biological nitrogen fixation. In Azotobacter vinelandii, it is a homodimer; each subunit contains one 2Fe-2S cluster [], which is proposed to have a redox function involving the release of Fe for the biosynthesis of the Fe-S cluster at the labile rubredoxin-like site []. |
