Crystals of the octameric histone core of the nucleosome.
The undegraded core histone octamer has been crystallized in a form suitable for x-ray analysis. The hexagonal bipyramidal crystals reproducibly grow larger than 1.0 by 0.6 millimeter, X-ray reflections are observed from Bragg planes with spacings larger than 3.5 angstroms. The crystals have the symmetry of the space group P3l21 or its enantiomorph. There appears to be one histone octamer per asymmetric unit.
