Interaction of the histone (H3-H4)2 tetramer of the nucleosome with positively supercoiled DNA minicircles: Potential flipping of the protein from a left- to a right-handed superhelical form.
We have studied the ability of the histone (H3-H4)2 tetramer, the central part of the nucleosome of eukaryotic chromatin, to form particles on DNA minicircles of negative and positive superhelicities, and the effect of relaxing these particles with topoisomerase I. The results show that even modest...
