Lineweaver burk plots for enzyme inhibition

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: NettetPLU is a competitive inhibitor of ScDHOase. PLU (50 μM) was included in the standard assay for analyzing the enzyme activity under different substrate concentrations. Inhibition of ScDHOase by PLU resulted in a Lineweaver–Burk plot where the lines cross the y-axis at a similar point, indicating that PLU is a competitive inhibitor for …

Lineweaver Burk Plots – MCAT Biochemistry MedSchoolCoach

When used for determining the type of enzyme inhibition, the Lineweaver–Burk plot can distinguish competitive, pure non-competitive and uncompetitive inhibitors. The various modes of inhibition can be compared to the uninhibited reaction. Vmax is unaffected by competitive inhibitors. Therefore competitive inhibitors have the same y-intercept as uninhibited enzymes (since Vmax is unaffected by competitive inhibitors the invers… Nettet1.
