New crystals of the histone core octamer diffract to higher resolution, 2.65 A.
A new crystal form of the histone octamer, crystallized in 1.6 M KCl, 1.6 M phosphate, diffracts to appreciably better than 2.6 A resolution. The crystals have space group P6(1) or P6(5) and lattice parameters a = b = 158.29, c = 103.27 A, alpha = beta = 90, gamma = 120 degrees, with one molecule per asymmetric unit. The new crystals promise to yield more detail of the histone basic domains and a higher resolution structure for the histone octamer.
