Extended Data Fig. 5: Comparison of FeP, MoFeP, and FeSII cryoEM structures from the 2:2:1 complex with corresponding crystal structures.
From: Structural basis for the conformational protection of nitrogenase from O2
a, ADP-bound FeP from the 2:2:1 complex aligned with the following X-ray crystal structures: AMPPCP-bound FeP (PDB ID: 4WZA), nucleotide-free FeP (PDB ID: 2AFH), and ADP-bound FeP (PDB ID: 2AFI). b, MoFeP from the 2:2:1 complex aligned with MoFeP from the crystal structure of the ADP-bound 2:1 FeP:MoFeP complex (PDB ID: 2AFI). c, FeSII from the 2:2:1 complex aligned with the symmetry mates of the “closed” FeSII subunit X-ray crystal structure (PDB ID: 6YAV).
