Ackers, in Advances in Protein Chemistry, 1998 C The Hill Coefficient. A traditional measure of cooperative interaction among the binding sites within a protein is the Hill coefficient n H = d ln [Y ¯ / (1 − Y ¯] / d ln x, which is usually determined as the slope of a logarithmically transformed binding curve (cf. Gutfreund and Edsall, 1978; Wyman and …

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. ...
