Abstract: Nitrogenase is a catalyst used by nitrogen-fixing microorganisms to convert atmospheric nitrogen into ammonia at ambient temperature and pressure. The structure of the active site in molybdenum nitrogenase has evolved from Fe2S2∙Mo2O2 to MoFe7S9C(R-Hhomocit)(cys)(his) (H4homocit = homocitric acid, Hcys = cysteine, Hhis = histidine) through advancements in chemical modeling, spectroscopy, and theoretical calculations, especially for structural biology. This paper provides a comprehensive review of the important achievements in the study of the active site of nitrogenase from a chemical structure perspective over the past fifty years.

Key words: Nitrogenase, MoFe-protein, FeMo-cofactor, Active site
