Evaluation of enzyme kinetic parameters to produce methanol using Michaelis-Menten equation

Determination of kinetic parameters of enzymes is important in biotechnology research. It is also one of the most challenging processes in methanol production. The activity of enzyme is determined in term of initial rates at various substrate concentrations. The enzymatic hydrolysis of methanol by p...
