Allosterism definition

WebJan 3, 2024 · In fact allosteric means “other site”. Because allosteric regulators do not bind to the same site on the protein as the substrate, changing substrate concentration generally does not alter their effects. Of course there are other types of regulation as well. A molecule may bind to and block the active site of an enzyme. WebAllosteric 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 ...
