WebThis is positive cooperativity. You can have a Hill coefficient that is as large as the number of subunits available, though just because you have 4 subunits doesn't necessarily mean the coefficient is 4. Just that it can't be any higher than that. If binding to one subunit makes it harder for other subunits to bind, that's negative cooperativity. WebMay 1, 2024 · The red box corresponds to the distribution of site/system-specific parameters (IC 50 s and Hill coefficients) within each site (intra-site variability).
