how is enzyme activity regulated
Precursor Activation. In the case if feedback inhibition and precursor activation, the activity of the enzyme is being regulated by a molecule which is not its substrate. In these cases, the regulator molecule binds to the enzyme at a different site than the one to which the substrate binds.When the regulator binds to its site, it alters the shape of the enzyme so that its activity is changed. This is called an allosteric effect.recursor Activation.
