    1. Nucleosome core histones [47114] (23) picpic
      form octamers composed of two copies of each of the four histones
    2. Archaeal histone [47129] (4) picpic
    3. TBP-associated factors, TAFs [47134] (13) picpic
    4. Bacterial histone-fold protein [101318] (2) picpic
      duplication: two repeats of histone fold are arranged as subunits in the archael histone dimer; new structure from Thermus thermophilus (1wws) comprised of dimers similar the to the H3-H4 tetramer
