A methyldiazene (HN [Image: see text] N [Image: see text] CH(3))-derived species bound to the nitrogenase active-site FeMo cofactor: Implications for mechanism

Methyldiazene (HN [Image: see text] N [Image: see text] CH(3)) isotopomers labeled with (15)N at the terminal or internal nitrogens or with (13)C or (2)H were used as substrates for the nitrogenase α-195(Gln)-substituted MoFe protein. Freeze quenching under turnover traps an S = ½ state that has bee...
