General Substrate Dependence of n_min. n_min vs. substrate concentration, measured in units of K_M. N_L determines the asymptotic limit at low substrate concentrations while N_S determines the asymptotic limit at saturating substrate concentrations. The parameter α determines the height of the peak between these two asymptotic limits. The solid red curve corresponds to N_L = 2.5, N_S = 1, and α = 0. The solid blue curve corresponds to N_L = 1, N_S = 3, and α = 0. The dashed lines correspond to the same values as the solid curves but with α = 0.3.
