WebThe Hill coefficient (nH), an often-used measure of deviations from hyperbolic behaviour (nonhyperbolicity) in kinetic and binding systems, is usually estimated from the maximum or minimum slope of the Hill plot. WebC The Hill Coefficient A traditional measure of cooperative interaction among the binding sites within a protein is the Hill coefficient nH = d ln ln x, which is usually determined as the slope of a logarithmically transformed binding curve (cf. Gutfreund and Edsall, 1978; Wyman and Gill, 1990 ).

WebMay 1, 2024 · Hill coefficient was bounded between 0.5 and 2.0, which was the range obtained by previous investigators after examination a large amount of HTS dose-response data (see (Elkins et al., 2013) and Supplementary Methods for details). WebThe only source of non-linearity in this model is a Hill function, characterizing the repression process. It was mathematically shown that to obtain limit-cycle oscillations, the Hill coefficient must be larger than 8, a value often considered unrealistic. It is indeed difficult to explain such a high coefficient with simple cooperative dynamics.
