The rate constants from Table 1 and Scheme 2 of Lowe &amp; Thorneley [(1984) Biochem. J. 224, 877-886] were used to simulate the rate of H2 evolution, under various conditions, from nitrogenase isolated from Klebsiella pneumoniae. These rates depend on both the ratio and concentrations of the MoFe protein and Fe protein that comprise nitrogenase. The simulations explain the shapes of 'protein titration' and 'dilution effect' curves. The concept of an apparent Km for the reductant Na2S2O4 is shown to be invalid, since the dependence of H2-evolution rate on the square root of S2O4(2-) concentration is not hyperbolic and depends on the ratio and absolute concentrations of the MoFe protein and Fe protein.
