Allosteric
Allosteric — A mode of receptor modulation where a compound binds at a site other than the active site, altering the receptor's response to its primary ligand.
What Does Allosteric Mean?
Allosteric refers to a regulatory mechanism in which a molecule binds to a site other than the active site (orthosteric site) of a receptor or enzyme, changing its shape and function. Allosteric regulation allows fine-tuning of biological responses without competing with the natural ligand. See allosteric modulation for detailed pharmacological context.
Allosteric Phenomena
- Enzyme regulation: Allosteric enzymes have sigmoidal kinetics and are regulated by metabolites
- Receptor modulation: PAMs and NAMs enhance or reduce endogenous peptide responses
- Hemoglobin: Classic allosteric protein showing cooperative oxygen binding
Frequently Asked Questions
