WebThe Hill coefficient of one gives a typical Michaelis-Menten hyperbolic response while Hill coefficient greater than one yields a sigmoidal curve with the inflection point at K 0.5. The analogy of the receptor-ligand interaction kinetics yielding Hill equation, can be applied to several biomolecular reactions such as binding of transcription ...

WebA 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 ). The maximum value of nH, or its value at half-saturation, is frequently ...
WebHalf maximal effective concentration ( EC50) is a measure of the concentration of a drug, antibody or toxicant which induces a response halfway between the baseline and maximum after a specified exposure time. [1] More simply, EC 50 can be defined as the concentration required to obtain a 50% [...] effect [2] and may be also written as [A] 50. [3] The Hill coefficient is a measure of ultrasensitivity (i.e. how steep is the response curve). The Hill coefficient, $${\displaystyle n}$$ or $${\displaystyle n_{H}}$$, may describe cooperativity (or possibly other biochemical properties, depending on the context in which the Hill–Langmuir equation is being used).

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.
