WebbThe Michaelis-Menten constant is defined as a substrate concentration at which the rate of reaction is half the maximum rate that can be achieved under the given conditions. It is denoted by the symbol Km. In other words, it is a substrate concentration at which the rate of reaction is half the Vmax. WebbProblem 3. Derive an expression for rate of product formation (reaction rate) in a michaelis-menten kinetics model with non-competitive inhibition as shown below: …

"WebbKm is theMichaelis-Menten constant, expressed in the same units as X. It describes the interaction of substrate and enzyme in the absence of inhibitor. If the data don't fit the model well, consider instead fitting to a noncompetitiveor uncompetitivemodel. Or fit to the more general equation for mixed-model inhibition.

Les inhibiteurs non-compétitifs sont des effecteurs allostériques (voir plus bas), puisqu'ils agissent ailleurs (allo-) que le site actif. WebbThe term non-competitive inhibitionis sometimes used instead of mixed inhibition,but this usage is discouraged, first because the same term is often used for the special case of mixed inhibition in which Kic= Kiu, second because it suggests that mixed inhibition is the antithesis of competitive inhibition whereas this description actually applies …

WebbKinetic constants were obtained by a nonlinear regression analysis of experimental data fitted to the Michaelis–Menten equation with competitive, non-competitive and mixed-type inhibition models (GraphPad Prism version 6 software). Kinetic analysis was also shown by using the Lineweaver–Burk plot. WebbSubsequently, different concentrations of the pNPG (0.2275–0.91 mM) were added, and the absorbance of the sample was measured at 405 nm. The Michaelis constant (K m) and the maximum reaction rate (V max) were obtained by the Michaelis-Menten equation through non-linear regression method in Graphpad Prism 5 (GraphPad Software Inc., …
