C. Indicated concentrations (0.25 to 16 μM) of purified recombinant Kap114p were incubated with yTBP (4 μM) and FAM-labeled DNA (5 nM), followed by native PAGE analysis. Kap114p (16 μM) was incubated with DNA without yTBP as a control. Band intensities of free DNA from the gels (Top panel) were quantified and plotted (Bottom panel).
