WebWhen a ligand binds to a cell-surface receptor, the receptor’s intracellular domain (part inside the cell) changes in some way. Generally, it takes on a new shape, which may make it active as an enzyme or let it bind other molecules. The change in the receptor sets off a series of signaling events. WebThese enzymes, which include some of our key metabolic regulators, are often given the name of allosteric enzymes 2 ^2 2 squared.
