Lineweaver–burk plot inhibition

NettetPrepare Lineweaver-Burk plots of the kinetic data and fit the data using linear regression (1 fit per inhibitor concentration). Calculate K m by dividing the slope of any of these … Nettet7. mar. 2024 · The Lineweaver–Burk plot for inhibited enzymes can be compared to no inhibitor to determine how the inhibitor is competing with the enzyme. [2] The Lineweaver–Burk plot is correct when the enzyme kinetics obey ideal second-order kinetics, however non-linear regression is needed for systems that do not behave ideally.

Nettet14. jan. 1999 · The Lineweaver-Burk equation in the presence of an uncompetitive inhibitor is: (8.12) and the slope of a Lineweaver-Burk plot is equal to: (8.13) In other words, the slope of a Lineweaver-Burk plot is not altered by the presence of an uncompetitive inhibitor, but both intercepts change ( Fig. 8.6 ). 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. Competitive Inhibition Vmax is unaffected by competitive inhibitors. … Se mer In biochemistry, the Lineweaver–Burk plot (or double reciprocal plot) is a graphical representation of the Lineweaver–Burk equation of enzyme kinetics, described by Hans Lineweaver and Dean Burk in 1934.
