In accordance with the results of classical experiments performed in vitro with calf thymus chromatin and the fish protamine salmine, we have observed that this highly basic, small molecular weight protamine cannot cause major displacement of histones from nucleosomal core particles at concentrations several times higher than physiological (arginine/nucleotide ratios 1-8) and that hyperacetylation of histones facilitates nucleosome disassembly. However, the avian protamine galline, with… CONTINUE READING
