  1. Ribbon representation of Mo­nitrogenase MoFe protein alpha2ß2 tetramer structure (PDB code 2MIN). Subunit colour­codes: alpha1 (chain A) = violet; ß1 (chain B) = green; alpha2 (chain C) = yellow; ß2 (chain D) = orange.
  2. Ribbon representation of Mo­nitrogenase MoFe protein alphaß dimer structure (orientation as a). Subunit colour­codes: alpha1 (chain A) = violet; ß1 (chain B) = green.
  3. Ribbon representation of Mo­nitrogenase MoFe protein alpha1 subunit (chain A) structure (orientation as a). Domain colour­codes: domain I = dark blue; domain II = light blue; domain III = magenta.
  4. Ribbon representation of Mo­nitrogenase MoFe protein ß1 subunit (chain B) structure (orientation as a). Domain colour­codes: domain I' = light green; domain II' = cyan; domain III' = dark green.
  5. M­cluster (left), P­cluster (right), and their environment residues only (orientation as a rotated -40° around z axis).
  6. M­cluster and its environment residues.
  7. P­cluster: reduced or PN state (PDB code 2MIN) and its environment residues.
  8. P­cluster: oxidised or POX state (PDB code 3MIN) and its environment residues.
All drawings were produced by using the program MOLSCRIPT [2].
