Hill cooperativity

WebIf n is greater than 1 it is positive cooperativity and if n is less than 1 its negative cooperativity. If n = 1, it reduces to MM Equation. I use ENZYME KINETICS MODULE EK1 linked to Sigma-Plot. WebNegative cooperativity is a phenomenon in which the binding of a first ligand or substrate molecule decreases the rate of subsequent binding. This definition is not exclusive to ligand-receptor binding, it holds whenever two or more molecules undergo two successive binding events. What is Hill coefficient cooperativity?
