Asymmetry of chromatin subunits probed with histone H1 in an H1-DNA complex. 1978

K Hayashi, and T Hofstaetter, and N Yakuwa

Treatment of nucleosomes with a low concentration of sodium dodecyl sulfate removed all proteins except histone H1 from DNA, thus confirming our previous observation on sheared chromatin. No redistribution of H1 occurred during this procedure for isolation of the H1-DNA complex. The H1-DNA complex was isolated from a nucleosome monomer, doubly labeled in its protein and DNA and fractionated according to the length of DNA, and then the distribution of H1 was analyzed quantitatively. The results indicated that the monomer consisted of two subspecies, one containing 160 base pairs of DNA and one molecule of H1, and the other containing 140 base pairs of DNA and no H1. Since no monomer with two molecules of H1 was found, it is concluded that the nucleosome core has a binding site for H1 on only one side, and thus that the nucleosome is not a dyad.

D006657 Histones Small chromosomal proteins (approx 12-20 kD) possessing an open, unfolded structure and attached to the DNA in cell nuclei by ionic linkages. Classification into the various types (designated histone I, histone II, etc.) is based on the relative amounts of arginine and lysine in each.
