Labster enzyme kinetics.

The maximum possible velocity (Vmax) occurs when all the enzyme molecules are bound with substrate [ES] = [E] total, thus: V max = k 2 [E] total. Substituting this into the prior expression gives: V = V max [S] / (K m + [S]) This is the mathematical expression that is used to model your experimental kinetic data. It is known as the Michaelis ...Figure 1: Chemical formula of a reaction using the enzyme ADH and beneath it a structure of alcohol dehydrogenase ADH1B*1 (from PDB entry 1HSZ).

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.
