Analysis of this finding leads us to conclude that nitrogenase reduces N2H2, CH3N2H, and N2H4 via a common A reaction pathway, and that the same is true for N2 itself, with Fe ion(s) providing the site of reaction.EBSCO_AspJournal of the American Chemical Society...
When spectra recorded on samples prepared with the three isotopomers are compared, it is clear that the 13CH3 labeling strategy is the most beneficial from the perspective of sensitivity (gains ≥2.4 relative to either 13CH2D or 13CHD2 labeling), although excellent...
