Dissociation of Protamine‐DNA Complexes by Xenopus Nucleoplasmin and Minichromosome Assembly in vitro

Nucleoplasmin, an acidic thermostable protein abundant in the nucleus of Xenopus laevis oocytes, has been found to dissociate complexes of pUC19 DNA and protein φ1, an intermediate protamine present in ripe sperm from the mollusc Mytilus edulis. Cruder preparations of nucleoplasmin, such as the amph...
