  4. 1262430Superfamily a.22.1: Histone-fold [47113] (5 families) (S)

Families:

  1. 1262431a.22.1.1: Nucleosome core histones [47114] (6 proteins)
    form octamers composed of two copies of each of the four histones
  2. 1262924a.22.1.2: Archaeal histone [47129] (1 protein)
  3. 1262940a.22.1.3: TBP-associated factors, TAFs [47134] (14 proteins)
  4. 1263002a.22.1.4: Bacterial histone-fold protein [101318] (3 proteins)
    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
    automatically mapped to Pfam PF09123
  5. 1263019a.22.1.0: automated matches [238448] (1 protein)
    not a true family
