The structure of 10 is shown.
Values represent means ± standard error of the mean (SEM) from a minimum of three independent assays, each in triplicate or quadruplicate. Δ stands for the difference of Log(αβ/KB) from that of 1, positive values indicated increased allosteric activity and negative values indicated reduced allosteric activity. Proton concentration-response curves are shown in Supporting Figure 1.
