Lineweaver plot
NettetSame problem I am facing that when I am plotting Lineweaver-Burk plot, my Km and Vmax is coming negative. Can you suggest me to use the integrated Michaleis Menten equation for calculation of Km ... NettetA single band of the purified inhibitor was obtained by Native-PAGE. SDS–PAGE revealed the purified inhibitor to be a monomer with molecular weight of 13,900 daltons. The nature of inhibition was found to be of non-competitive type as determined by Lineweaver–Burk plot and a Ki value of 0.54nmole was obtained by Dixon's plot.

Nettet14. apr. 2024 · In this lecture, we explain the double reciprocal plot, a graphical method commonly used for the accurate determination of the Km and Vmax of enzymes. NettetUse. The Lineweaver-Burk plot was widely used to determine important terms in enzyme kinetics, such as K m and V max before the wide availability of powerful computers and non-linear regression software, as the y-intercept of such a graph is equivalent to the inverse of V max; the x-intercept of the graph represents -1/K m.

NettetV_ {max} V max is the Y-value (initial rate of reaction value) at which the graph above plateaus. The substrate concentration that gives you a rate that is halfway to V_ {max} V max is called the K_m K m, and is a useful measure of how quickly reaction rate increases with substrate concentration. K_m K m is also a measure of an enzyme's ... NettetThe Lineweaver Burk plot is a graphical representation of enzyme kinetics. The x-axis is the reciprocal of the substrate concentration, or 1 / [S], and the y-axis is the reciprocal …
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. The Lineweaver–Burk plot for inhibited enzymes can be compared to no inhibitor to determine … Se mer $${\displaystyle [S]}$$: substrate concentration. The independent axis of a Lineweaver-Burk plot is the reciprocal of substrate concentration, $${\displaystyle {\frac {1}{[S]}}}$$. $${\displaystyle V}$$ Se mer The plot provides a very useful graphical method for analysis of the Michaelis–Menten equation, as it is difficult to determine precisely the Vmax of an enzyme-catalysed reaction: $${\displaystyle V={\frac {V_{\max }[S]}{K_{m}+[S]}}}$$ Se mer While the Lineweaver-Burk is useful for determining important variables in enzyme kinetics, it is prone to error. The y-axis of the plot takes the reciprocal of the rate of reaction, meaning small errors in measurement are more noticeable. Additionally, the … Se mer 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.
