Measurements of kinetic parameters of SARS main protease. The reaction initial rates of the protease under a variety of different substrate concentrations were plots against substrate concentrations to obtain the Vmax and Km values of the enzyme. KaledaGraph computer program was used to fit the kinetic data using Michaelis–Menten equation.
