WebHill coefficient ( 1 is the middle): measures cooperative binding. Below 1 is negative cooperativity, where as more than 1 is positive. Catalytic efficiency= kcat/km. This basically measures how good an enzyme is. [deleted] • 6 yr. ago Km is affinity (Higher = lower affinity to bind) aka more substrate needs to bind to reach half of Vmax. WebFor myoglobin, which only has one subunit, the slope must be 1; for hemoglobin, the Hill coefficient is 2.8, indicating a minimum of three interacting subunits, although there are four subunits in a molecule of hemoglobin.

If it is positive, the curve increases as X increases. If it is negative, the curve decreases as X increases. A standard sigmoid dose-response curve (previous equation) has a Hill Slope of 1.0. When HillSlope is less than 1.0, the curve is more shallow.

WebAug 12, 2016 · The Hill equation describes the binding of a ligand to a macromolecule is often enhanced if there are already other ligands present on the same macromolecule. The hill coefficient provides a way to quantify this effect. A coefficient of 1 indicates completely independent binding, regardless of how many additional ligands are already bound. The EC50 relates to the Hill equation, which is a function of the agonist concentration, [A]: where E is the observed response or effect above baseline, and nH, the Hill coefficient reflects the slope of the curve. The EC50 represents the point of inflection of the Hill equation, beyond which increases of [A] have less impact on E. In dose response curves, the logarithm of [A] is often taken, turning the Hill equ…
