allosteric site

allosteric

[al″o-ster´ik] pertaining to an effect produced on the biological function of a protein by a compound not directly involved in that function (an allosteric effector) or to regulation of an enzyme involving cooperativity between multiple binding sites (allosteric sites).allosteric site that subunit of an enzyme molecule which binds with a nonsubstrate molecule, inducing a change in form or shape that results in inactivation of the enzyme for its substrate.

al·lo·ste·ric site

postulated as the place on an enzyme, other than the active site, where a compound, which may be the ultimate product of the biosynthetic pathway involving the enzyme, may bind and influence the activity of the enzyme by changing the enzyme's conformation; the influence of CTP on aspartate carbamoyltransferase activity exemplifies the concept of an allosteric site on an allosteric protein.

al·lo·ste·ric site

(al'ō-ster'ik sīt) Postulated as the place on an enzyme, other than the active site, where a compound, which may be the ultimate product of the biosynthetic pathway involving the enzyme, may bind and influence the activity of the enzyme by changing the enzyme's conformation.

allosteric site

a functional on/off switch for an enzyme situated away from its active site.
