NettetHanes–Woolf plot. In biochemistry, a Hanes–Woolf plot, Hanes plot, or plot of against , is a graphical representation of enzyme kinetics in which the ratio of the initial substrate concentration to the reaction velocity is plotted against . It is based on the rearrangement of the Michaelis–Menten equation shown below: NettetThis qualitative approach to enzyme inhibition starts by recognizing that the two fundamental kinetic parameters of an enzyme catalyzed reaction are V (max) and V (max) /K (m) , which correspond to the apparent rates of reaction at very high and very low concentrations of substrate, respectively.

As shown in Figure 13.14, when we display kinetic data using as a Lineweaver-Burk plot it is easy to determine which mechanism is in effect. For example, an increase in slope, a decrease in the x-intercept, and no change in the y-intercept indicates competitive inhibition.
