Webb12 mars 2024 · Enzyme inhibition is most commonly analyzed using initial velocity measurements. Formally, the initial velocity is determined from a tangent to the initial portion of the reaction progress curve, and it is most convenient to use a continuous assay format so that the initial velocity can be accurately measured. Webbreverses the inhibitory action of ATP. Therefore, the activity of the enzyme increases when the cellular ATP/AMP ratio is lowered. Glycolysis is thus stimulated when energy charge falls. PFK1 has two sites with different affinities for ATP, which is both a substrate and an inhibitor. ATP is the final product of glucose catabolism (glycolysis ...
