title: Histone-DNA contacts in the 167 bp 2-turn core particle.
abstract: The histone-DNA contacts in the 167 bp 2-turn core particle have been compared with those in the 146 bp 1.75-turn core particle by the methodology developed by Mirzabekov and his colleagues. The contacts in the 167 bp 2-turn core particle retain the essential features of those in the 146 bp 1.75-turn core particle but contacts for histones H3 and H2A were found in the 10 bp extension that discriminates the two particles. In addition the contact for histone H2A near the dyad axis was far more pronounced in the case of the 146 bp core particle.
