An allosteric site is a specific location on an enzyme or protein that is distinct from the active site, where the binding of a molecule can lead to a change in the protein's conformation and function. This binding can either enhance or inhibit the activity of the enzyme, affecting how substrates interact with the active site. Allosteric sites play a crucial role in regulating metabolic pathways and are essential for processes like cooperativity and allosteric regulation.
congrats on reading the definition of allosteric site. now let's actually learn it.
