WebThus, the Hill coefficient defines cooperativity as a statistical dependence of one binding site on the state of other site(s). The Klotz equation Working on calcium binding proteins, Irving Klotz deconvoluted Adair's association constants by considering stepwise formation of the intermediate stages, and tried to express the cooperative binding ... WebHill coefficient: ( hil ), the slope of the line in a Hill plot; a measure of the degree of cooperativity. Synonym(s): Hill constant

New Interpretation of the Hill Coefficient SpringerLink

WebThe degree of cooperativity is determined by Hill equation (Equation 3.6.1) for non-Michaelis-Menten kinetics. The Hill equation accounts for allosteric binding at sites other than the active site. n is the "Hill coefficient."

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). When … See more In biochemistry and pharmacology, the Hill equation refers to two closely related equations that reflect the binding of ligands to macromolecules, as a function of the ligand concentration. A ligand is "a substance that … See more The Hill-Langmuir equation is derived similarly to the Michaelis Menten equation but incorporates the Hill coefficient. Consider a protein (), such as haemoglobin or a protein receptor, with $${\displaystyle n}$$ binding sites for ligands (). The binding of the … See more Because of its assumption that ligand molecules bind to a receptor simultaneously, the Hill–Langmuir equation has been criticized as a physically unrealistic model.
