Vmax = k2[E]0. and after rearrangement, we have this equation: kcat = k2 = Vmax [E]0. That is the equation for calculating catalytic efficiency, to be used after we obtain data from experiments and after using the Michaelis-Menten equation. With a larger k cat , the enzyme is efficient because less enzyme is needed.
