How to Reduce Stress Through Mind-Body Therapies

WebAllosteric activators can increase reaction rates. They bind to an allosteric site which induces a conformational change that increases the affinity of the enzyme's active site for its substrate. This increases the reaction rate. Cofactors and Coenzymes Many enzymes only work if bound to non-protein helper molecules called cofactors and coenzymes. WebAllosteric enzymes typically have multiple active sites located on different protein subunits. When an allosteric inhibitor binds to an enzyme, all active sites on the protein subunits are changed slightly so that they work less well. There are also allosteric activators.
