Alanine is a non-competitive inhibitor, therefore it binds away from the active site to the substrate in order for it to still be the final product. [6] Another example of non-competitive inhibition is given by glucose-6-phosphate inhibiting hexokinase in the brain. Carbons 2 and 4 on glucose-6-phosphate contain hydroxyl groups that attach ...
If the inhibitor is different from the substrate, then competitive inhibition will increase Km while Vmax remains the same, and non-competitive will decrease Vmax while Km remains the same. However, under substrate inhibiting effects where two of the same substrate molecules bind to the active sites and inhibitory sites, the reaction rate will ...
On the other hand, the V max will decrease relative to an uninhibited enzyme. On a Lineweaver-Burk plot, the presence of a noncompetitive inhibitor is illustrated by a change in the y-intercept, defined as 1/V max. The x-intercept, defined as −1/K M, will remain the same. In competitive inhibition, the inhibitor will bind to an enzyme at the ...
a possible mechanism of non-competitive inhibition, a kind of mixed inhibition.. Mixed inhibition is a type of enzyme inhibition in which the inhibitor may bind to the enzyme whether or not the enzyme has already bound the substrate but has a greater affinity for one state or the other. [1]
With pure noncompetitive inhibition the apparent value of is decreased. This can be seen on the Lineweaver–Burk plot as an increased ordinate intercept with no effect on the abscissa intercept /, as pure noncompetitive inhibition does not effect substrate affinity.
For example, an inhibitor might compete with substrate A for the first binding site, but be a non-competitive inhibitor with respect to substrate B in the second binding site. [26] Traditionally reversible enzyme inhibitors have been classified as competitive, uncompetitive, or non-competitive, according to their effects on K m and V max. [14]

Enzyme-catalyzed reactions lower the overall activation energy of a reaction. The transition state of a structure can best be described in regards to statistical mechanics where the energies of bonds breaking and forming have an equal probability of moving from the transition state backwards to the reactants or forward to the products.
