WebFrom Vmax, we can calculate the turnover number kcat = Vmax / [E 0 ] (units: s-1) of an enzyme, which is the number of substrate molecules converted to product in a given unit of time on a single enzyme molecule when the enzyme is saturated with substrate. In the classic Michaelis-Menten mechanism, kcat = k 2. Lineweaver- Burk plot WebWhat this means that KM which we call the Michaelis constant is defined as the concentration of substrate at which our reaction speed is half of the Vmax. When Vo is equal to 1/2 of Vmax. If we look at that on a graph from before you'd see that KM is a substrate concentration specific to our circumstances.
