Legend Supplementary Figure 7: A) Force extension curves of HMfA in the absence and the presence of 2 mM Mg2+, as indicated. B-F) The histograms of stacking energy, wrapping energy, stiffness, bending angle, and number of bound dimers of HMfA in the absence and the presence of Mg2+ The histograms were fitted with a normal distribution. The mean and standard error of the mean of all fit parameters can be found in Table 2.
 
*** The data was obtained using magnetic tweezers as described in the associated article (See Supplementary Method for a description of the statistical mechanics model)

*** Data used for generating histograms and fits:

Column A: G1 (stacking energy in kT)
Column B: G2 (wrapping energy in kT)
Column C: N dimer (number of dimers bound to the DNA substrate)
Column D: angle (bending angle in degrees)
Column E: K (stiffness in pN/nm)
