Figure 10From: Mass action models versus the Hill model: An analysis of tetrameric human thymidine kinase 1 positive cooperativityThe model K = (10-6, 10-3, 1, 103) and k = (100, 10, 40, 10). Horizontal lines are k1/4, 2k2/4, 3k3/4 and 4k4/4 and vertical lines are concentrations of [ST] at which half the species are [ESi] and the other half are [ESi+1]; from Eq. (8) the vertical lines are at K1/4, 2K2/3, 3K3/2 and 4K4.Back to article page
