WebWhen enzymes contain more than one active site, the binding of a substrate molecule to the first site may influence substrate binding to a second site. Binding of the second substrate may influence binding of a third, and so on. … WebCooperativity. Cooperative binding are binding events in which the Binding Affinity of a molecule to an interaction partner is influenced by a preceding binding event. There are two kinds of cooperative binding. Homotropic cooperativity means that the binding of molecule A to a molecule B increases or decreases the affinity of B for further molecules …

For two identical sites, if the second binding is weaker once the first site is occupied, this is called negative cooperativity. The opposite corresponds to positive cooperativity.

The Hill coefficient is a measure of ultrasensitivity (i.e. how steep is the response curve). The Hill coefficient, or , may describe cooperativity (or possibly other biochemical properties, depending on the context in which the Hill–Langmuir equation is being used). When appropriate, the value of the Hill coefficient describes the cooperativity of ligand binding in the following way: • .
