WebDec 1, 2003 · The term allostery means “other sites.” Allosteric proteins, such as hemoglobin, are “intelligent” molecules that vary their activity in response to environmental stimuli in the form of concentration changes of ligands, such as ions, metabolites, and macromolecules. 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 ...
