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. … 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: • . Positively cooperative binding: Once one ligand molecule is bound to the enzyme, its affinity f…
