Fig. 7.
(A) DNA stretch (solid line) and release (dotted line) curves in the absence of protein (black) and in the presence of 50 nM FIV NC K28A/R29A (red) and 200 nM FIV NC K28A/R29A (blue). (B) DNA stretch (solid line) and release (dotted line) curves in the absence of protein (black) and in the presence of 50 nM FIV NC ΔC21 (red) and 200 nM FIV NC ΔC21 (blue). (C) Slope of the transition of FIV NC WT (black), ΔC21 (red) and K28A/R29A (green). (D) Hysteresis versus concentration of FIV NC WT (black), ΔC21 (red) and K28A/R29A (green). Error bars are propagated from the uncertainty in the force-extension measurements.
