4.5.5. Allosteric enzymes

Allosteric enzymes

The allosteric enzymes are enzymes regulated by binding of a molecule called modulator or allosteric effector, to a site other than the active site, called allosteric site.

Like the active site, also the allosteric site is specific for each modulator. Modulators can be negative or inhibitory or positive or activating, depending on whether they inactivate or activate the enzyme, respectively.
