"Allosteric enzymes are enzymes that change their conformational ensemble upon binding of an effector (allosteric modulator) which results in an apparent change in binding affinity at a different ligand binding site. This "action at a distance" through binding of one ligand affecting the binding of another at a distinctly different site, is the essence of the allosteric concept. Allostery plays a crucial role in many fundamental biological processes, including but not limited to cell signaling a… " - Allosterische enzymregulation

WebAbstract. Allosteric regulation refers to the process for modulating the activity of a protein by the binding of a ligand, called an effector, to a site topographically distinct from the site of the protein, called the active site, in which the activity characterizing the protein is carried out, whether catalytic (in the case of enzymes) or ...
