Abstract

The methods of Atkins & Nimmo (1973) and Fernley (1974) for fitting the integrated Michaelis–Menten equation were compared by using the same sets of simulated experimental data. The method of Fernley (1974) is to be preferred because it gives precise and unbiased estimates of the Michaelis–Menten parameters over a wide range of substrate concentrations. However, the estimates may not be symmetrically distributed, especially at low substrate concentrations.
