The existence of histone HI has been questioned in Trypanosomatids. We report here the presence of a histone HI in the chromatin of Trypanosoma cruzi. This protein was purified by narrow-bore reversed phase HPLC and its amino acid composition analyzed and compared with histones HI from other species
Nucleosomal subunits isolated from rabbit thymus nuclei in 0.04 M K2SO 4-0.02 M Tris, pH 7.4 were devoid of histone H1, while whole chromatin prepared in the same buffer contained the full complement of histone HI. The question is asked why histone H1 dissociates from the subunits but not from the h
