Nucleic Acids Res. , 32, pp. 1097 - 1102, 2004.
Experimental Information:X-RAY DIFFRACTION
Space Group: 21   1
Cell Constants:
a = 28.319b = 56.341c = 51.746(Ångstroms)
= 90.00 = 99.17 = 90.00(degrees)
Crystallization Conditions:
Drop:PEG 400 sodium cacodylate, magnesium chloride, spermine, tetrahydrochlorhide, thallium acetate, lysine-anthraquinone, H2O
Reservoir:PEG 400 magnesium chloride, thallium acetate, sodium cacodylate, H2O
Refinement:The structure was refined using the CNS 1.1 program. The R value is 22.4 for 4281 reflections in the resolution range 19.84 to 2.50 Ångstroms with Fobs > 2.000 sigma(Fobs).
