Allosteric site
Allosteric site | A binding site on the surface of an enzyme separate from the active site. In non-competitive inhibition, binding of an inhibitor to an enzymes allosteric site inhibits the activity of the enzyme. In allosteric enzymes the binding of the regulatory molecule to the allosteric site can either enable substrate binding or inhibit substrate binding to the active site. Thus, either allowing formation of an enzyme-substrate complex or inhibiting it, thereby regulating the synthesis of a product.
