Allosteric Inhibition - The Definitive Guide Biology Dictionary

Weballosteric control, in enzymology, inhibition or activation of an enzyme by a small regulatory molecule that interacts at a site (allosteric site) other than the active site (at which catalytic activity occurs). WebInhibition and activation of enzymes via other molecules are important ways that enzymes are regulated. Inhibitors can act competitively or noncompetitively; noncompetitive inhibitors are usually allosteric ( allo (other) steric (form). Activators can also enhance the function of enzymes allosterically.
