DNA shape recognition determines the preferred binding sites for
sequence-independent DNA binding proteins, and here we document that
archaeal histones assemble archaeal nucleosomes in vitro centered
preferentially within (CTG)6 and (CTG)8
repeats, close to junctions with flanking mixed-sequence DNA. Archaeal
nucleosomes were not positioned by (CTG)4-,
(CTG)5-, or
(CTG)3AA(CTG)3-containing DNA sequences. The
features of CTG repeat-containing sequences that direct eucaryal
nucleosome positioning may also be similarly recognized by archaeal histones.
