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?

WebMay 12, 2016 · In either case, the greater the positive cooperativity, the more switchlike or ultrasensitive the response is (Fig. 1, C and D, blue curves), and as c approaches infinity, the effective Hill exponent (n H) for the response approaches 2. Conversely, the stronger the negative cooperativity, the more graded the response is (Fig. 1, C and D, red ... WebHill coefficients represent the level of cooperativity for an enzyme. Greater than 1 is cooperativity, less than 1 is negative cooperativity and exactly 1 is no cooperativity. The Hill Coefficient of 4 looks like a sigmoidal "S" shaped curve demonstrating cooperativity, which means that as more substrate binds, the affinity increases.
