Structural basis for the conformational protection of nitrogenase from O₂

doi:10.1038/s41586-024-08311-1

Cryo-electron microscopy of Azotobacter vinelandii FeSII–nitrogenase reveals a core complex of molybdenum–iron proteins (MoFePs), iron proteins (FePs) and FeSII, in which FeSII mediates interactions with MoFeP and FeP to position their FeS clusters in catalytically inactive but O2-protected states.
