The data are shown with the results of a global fit to Scheme 1. Individual curves for each of the enzyme concentrations used are shown: 8 μM (red); 3 μM (green); 2 μM (blue); 1 μM (cyan); 0.5 μM (magenta) and 0.2 μM (purple), all reactions were performed with 0.1 μM substrate and other conditions as described in the Materials and methods section
