To calculate the vmax and km of the reaction you will need to run various concentrations of the methyltransferase to be tested and calculate the activity at each concentration. It is important to determine the km and vmax for a certain enzymatic activity because knowing these values allows us to predict the metabolic fate of the substrate and the relative amount of substrate that will go through each pathway under different conditions.
