Archaeal nucleosome positioning sequence from Methanothermus fervidus.
DNA in Methanothermus fervidus, a hyperthermophilic archaeon, is constrained into archaeal nucleosomes in vivo by the archaeal histones HMfA and HMfB. Here, we document the translational and rotational positioning of archaeal nucleosome assembly in vitro by a sequence from the 7S RNA encoding region of the M. fervidus genome. The minor groove of the DNA at the center of the DNA sequence, protected from micrococcal nuclease digestion by incorporation into a positioned archaeal nucleosome, faces away from the archaeal histone core.
