The Woolf-Augusteinsson-Hofstee plot of ? versus ? /[S
Eadie-Hofstee plot for a simple Michaelis-Menten enzyme reaction. Note that the slope gives the value of -Km and the ordinate intercept gives the value of Vmax. Note that the slope gives the value of -Km and the ordinate intercept gives the value of Vmax.... you plot v (Y-axis) against v/[S] (X-axis, [S] is substrate conc; intersection of linear graph at v = 0 with X-axis is Vmax/Km; -Km is slope

Of these, the double reciprocal plot is preferred to test for the qualitative correctness of a proposed mechanism, and the Eadie-Hofstee plot is preferred for discovering deviations from …
Does anyone have the original paper for "Eadie-Hofstee" plot?
The Eadie-Hofstee plot is a graph of v/[S] versus v and the Hanes-Woolf plot graphs [S]/v versus [S] a) in both cases, show that the equation being graphed can be derived from the Michaelis Menten Equation by simple arithmetic manipulation how to cancel friend suggested on linkedin In order to determine the appropriate type of inhibitor, develop a Lineweaver-Burk plot for the maltose trials. The graph is on the following page. By looking at it, we can see that both the The graph is …
Enzyme Kinetics Single Substrate Eadie-Hofstee Plot
Draw a sketch of a Lineweaver Burk plot showing how enzyme activity will change in the presence and absence of a competitive inhibitor; indicate where the parameters Km and Vmax can be calculated from. corel draw how to match pms colour Lineweaver-Burk, Hanes, Eadie-Hofstee and Dixon plots can only be used when a true initial rate is measured. Despite the fact that this point has often been stressed, it is far too often ignored in favour of restricting the assay time to one where low amounts of substrate are used.

How To Draw Eadie Hofstee Plot
a graphic representation of enzyme kinetic data in which velocities, v, are plotted on the vertical axis as a function of the v:[S] ratio on the horizontal axis. On occasion, these axes are reversed. Sometimes referred to as the Eadie-Augustinsson plot or Woolf-Eadie-Augustinsson-Hofstee plot
- Plots like this (I preferred the Eadie-Hofstee plot) were hacks that were useful when data were plotted on graph paper and constants extracted by eyeballing the best fit with a ruler. I stopped using them in the mid 80’s when freeware programs to do non-linear least-squares curve-fitting became available.
- Page 3 of 3 6. Main idea: M-M plot of v vs. [S] gives a hyperbola. Although we can use Excel or other tools to estimate v max and K m from this curve, it’s hard to draw an accurate curve by hand.
- Enzyme Kinetics - Single Substrate, Eadie-Hofstee Plot. This applet requires you to systematically vary the apparent K m s and V max s of an enzyme acting on a single substrate, subject to inhibition by an inhibitor, I, until a satisfactory fit to all experimental data is obtained.
- The "Eadie-Hofstee plot" in enzyme kinetics has v/S on the X axis and v on the Y axis (v is the reaction rate and S is the substrate concentration).
