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. WebAllostery is the process by which remote sites of a system are energetically coupled to elicit a functional response. The early models of allostery such as the Monod–Wyman–Changeux model and the Koshland–Némethy–Filmer model explain the allosteric behavior of multimeric proteins. harry\\u0027s kitchen uk
